1.1 Recent EUVE Science Highlights
----------------------------------
by Dr. Pierre Chayer, EUVE/CEA Scientist
o Light Curve Obtained of 5.75 millisecond Pulsar EUVE J0437-4715
Jules Halpern, Chris Martin, and Herman Marshall obtained a
light curve of the 5.75 millisecond pulsar J0437-4715 using the
Deep Survey instrument on the EUVE satellite.
This is the first EUVE observation to make use of the full 0.5
millisecond time resolution of the spacecraft clock in WSZ mode.
The single-peaked pulse profile contains approx 4200 photons, and
is the result of correcting the photon arrival times from the
satellite to the solar system barycenter, as well as from the
pulsar to the center of mass of its 5.74 day binary orbit. It is
not yet established whether the observed emission (from this or any
recycled pulsar) is non-thermal from the magnetosphere, or surface
thermal emission from a hot polar cap.
A combined analysis of the EUVE and ROSAT data, to appear in The
Astrophysical Journal, is used to place limits on the temperature
and surface area of thermally emitting regions that might be
present.
1.2 Abstracts of Recently *Accepted* EUVE Papers

EVIDENCE FOR WIND ATTENUATION AND A MULTI-TEMPERATURE PLASMA IN THE
COMBINED EUVE AND ROSAT OBSERVATIONS OF EPSILON CANIS MAJORIS (B2 II)
D.H. Cohen, R.G. Cooper, J.J. MacFarlane, S.P. Owocki, J.P.
Cassinelli, and P. Wang
To appear in the Astrophysical Journal.
We use both EUVE and ROSAT data sets to test three general pictures
-- coronal, wind shock, and external -- for the production of the
observed high energy emission from the B giant, epsilon CMa (B2 II).
Because of the very low interstellar opacity along its line of sight,
epsilon CMa is the only early-type star that has strong emission lines
detected with the EUVE spectrometers. The line spectrum provides the
first solid observational evidence that the emission is thermal.
Theoretical EUV spectra based upon two-temperature model fits to the
ROSAT data predict too much flux, especially in the iron line complex
near 175 Angstroms. We use progressively more complex models until we
are able to achieve a fit to the combined data sets. We find that
both a temperature distribution in the emitting plasma and some
attenuation of the EUV and soft X-ray emission by the ionized stellar
wind must be included in the models. The model fitting indicates that
only 13 to 21 percent of the emission line complex near 175 Angstroms
escapes the wind. This amount is consistent with the wind shock
model, in which the emitting material is distributed throughout the
stellar wind. It is much more absorption than is predicted by the
external source model, where all of the emitting material is at radii
beyond the cold stellar wind. And it is significantly less absorption
than is expected in the coronal model, given what is known about the
star's mass loss rate. The derived temperature distribution and wind
filling factor of hot gas are also qualitatively consistent with our
numerical simulations of wind shocks. We conclude that although the
observed flux from epsilon CMa in the interval 54 eV < E < 100 eV is
approximately the same as that above 100 eV, because of wind
attenuation the total generated radiation in the EUV band between 54
eV and 100 eV is 5 times greater than that in the X-ray region.

ASTRONOMIA PARA LA FAMILIA: A PROGRAM FOR NASA EDUCATION OUTREACH
RELYING ON PARENTAL INVOLVEMENT, HANDS-ON ACTIVITIES, AND
APPROPRIATE USE OF THE WORLD WIDE WEB
I. Hawkins and R.F. Malina
Presented at the International Astronautical Federation, Symposium: P,
Space and Education Symposium, Session: P2, Education Structures,
1995. [CEA publication #678]
We describe the bilingual Astronomia Para La Familia/Family
Astronomy Project, which is a bilingual (Spanish-English) education
outreach project of UC Berkeley's Center for EUV Astrophysics. The
project develops and operates weekend astronomy and space science
workshops for 7-8 grade students and their parents of Hispanic
background. The project is patterned on the successful Family Science
and Family Math programs from UC Berkeley's Lawrence Hall of Science.
Family Astronomy has been designed and implemented in collaboration
with UC Berkeley`s Graduate School of Education, the East Bay
Consortium (a non-profit organization that develops education programs
involving students and teachers of the Oakland Unified School
District), and the Association of Mexican Professionals of Silicon
Valley. The collaboration also involves Professor Emily van Zee from
the University of Maryland's College of Education and a graduate
student from the UC Berkeley School of Education to help guide the
design and assess the effectiveness of the program. The workshops
will be pilot-tested in fall of 1995 during weekend activities for 7-8
grade students and their families as part of East Bay Consortium
programs. This project investigates methods by which collaboration
among teachers, other professional educators, scientists, and families
can help increase (a) middle-school students' and their parents'
interest in science as well as (b) parental involvement in the science
education of their children. The study focuses on collaborative
science activities enhanced by images and data accessible through
World Wide Web technology carried out in an informal and supportive
setting.
The workshops focus on hands-on activities requiring child and
parent participation that demonstrate explicit concepts in astronomy
and space science. Such activities include observations of
astronomical objects using the naked eye and measuring instruments
constructed during the workshops, such as a simple astrolobe. The
program includes a visit to the satellite operations center for the
NASA Extreme Ultraviolet Explorer Satellite at the University of
California, Berkeley, and involves workshop participants in using the
Internet to access astronomy and space science data on the World Wide
Web. All the project materials, activities, and methods are being
documented on the CEA Education World Wide Web pages (URL:
http://www.cea.berkeley.edu). The CEA's Science Information
Infrastructure NASA-funded project disseminates the materials to
collaborating science museums such as the Exploratorium and Lawrence
Hall of Science.

GRAZING INCIDENCE OPTICS IN EXTREME ULTRAVIOLET ASTRONOMY
S. Bowyer
In X-Ray and EUV/FUV Spectroscopy and Polarimetry, ed. S. Fineschi,
Proceedings of SPIE 2517, 90-96, 1995. [CEA publication #679a]
The development of grazing incidence optics for extreme ultraviolet
(EUV) astronomy occurred in a vastly different science-political
environment than that of X-ray astronomy. X-ray astronomy had been
proven as an extremely useful field of research, and in the
environment of the 1960s funds were available for X-ray glass mirror
systems costing tens of millions of dollars for a single telescope. In
that era, EUV astronomy had not yet been demonstrated as a viable
field, and indeed, the general belief was that only a few astronomical
sources would be observable in this band. In that environment there
was no hope of obtaining funding for EUV telescopes similar to those
used in X-ray astronomy. As a consequence, an entirely different
approach was employed in the development of EUV grazing incidence
optics.
The general approach was to attempt to make grazing incidence EUV
optics out of metal. In the end, the best of these optics were as good
as the X-ray glass optics developed for the Einstein Observatory, but
with a cost of 1/20 of the Einstein mirrors.
The various technologies developed in order to carry out EUV
astronomy are discussed with an emphasis on EUV grazing incidence
mirrors. A report of a few of the astronomical results obtained
through the use of these optics are presented.

HIGHLIGHTS OF RECENT RESULTS FROM THE EXTREME ULTRAVIOLET EXPLORER
S. Bowyer
To appear in Proceedings of Frascati Workshop 1995, held in Vulcano,
Italy. [CEA publication #680]
From the beginnings of NASA in the late 1950's, the promise was
offered that the entire electromagnetic spectrum would be explored
providing new insights into stars, the Galaxy, and the universe.
There was one exception to this expansive view; the extreme
ultraviolet band of the spectrum, ranging from approximately 90 to 900
A, would be forever hidden from our view, because of severe absorption
due to the interstellar medium. Only in the early 1990s was this
overall appraisal shown to be incorrect with over 400 sources of
extreme ultraviolet radiation detected with the English Wide-field
camera on the German ROSAT satellite, (Pye et al. 1995) and more than
700 sources detected with NASA's Extreme Ultraviolet Explorer (EUVE;
Bowyer et al. 1995).
In the following, I would like to briefly comment on a few of the
results obtained with EUVE.
--------------------------------------------------------------
EUVE_J1429-38.0: A NEW MAGNETIC CATACLYSMIC VARIABLE
N. Craig, S.B. Howell, M.M. Sirk, and R.F. Malina
Astrophysical Journal Letters, 457, L91, 1996 [CEA publication #704]
The source EUVE_J1429-38.0 was discovered serendipitously by the
Extreme Ultraviolet Explorer( EUVE) satellite on 1993 March 5.
Optical spectroscopy confirms a cataclysmic-variable-type optical
counterpart for the source, showing Balmer, He I and Ca emission, as
well as strong He II emission. The optical spectrum, the apparent
high/low state behavior, and possible weak cyclotron humps visible in
the spectrum indicate that this star is likely to be an AM Herculis
system, but the possibility of being a DQ Her, or an unlocked AM Her
system cannot be excluded. Analysis of the highly modulated EUVE
photometry yields a period of 2 hr 22 min, which we conclude is the
binary orbital period. In addition, a 57 min period is also present.
An orbital period of 2.5 hr would make EUVE_J1429-38.0 only the third
known AM Her system within the cataclysmic variable period gap, all
three of which were discovered through EUV observations.

DISCOVERY OF 0.5 MILLION K GAS IN THE CENTER OF THE VIRGO CLUSTER
R. Lieu, J.P.D. Mittaz, S. Bowyer, F.J. Lockman, C.-Y. Hwang, and
J.H.M.M. Schmitt
Astrophysical Journal Letters, 458, L5, 1996. [CEA publication #705]
An observation of M87, the central galaxy of the Virgo cluster, was
performed by the Deep Survey (DS) telescope aboard EUVE, in the
0.065-0.245 keV energy band. A central source and an extended
emission halo of radius ~20 arcmin are clearly visible in the data,
and represent the first detection of cluster gas emission in the EUV.
The emission cannot be explained by the well-known cluster gas
(Fabricant & Gorenstein 1983; Forman, Jones, & DeFaccio 1985; Stewart
et al. 1984a; Bohringer et al. 1994) at X-ray temperatures. Instead,
it is necessary to introduce a second gas component, with temperature
between 5E+5 K and 1E+6 K. The rapid cooling of plasmas at such
temperatures implies a mass accretion rate of > 300 M_(solar) per
year. It is unlikely that the phenomenon is directly related to a
cooling flow, which involves a much lower accretion rate of ~10
M_(solar) per year.

EUVE RIGHT ANGLE PROGRAM OBSERVATIONS OF COOL STARS
D.J. Christian, J. Drake, and M. Mathioudakis
To appear in Proceedings of the 9th Cambridge Workshop, Cool Stars,
Stellar Systems, and the Sun, ed. R. Pallavicini and A. K. Dupree,
PASP Conf. Ser. (San Francisco: ASP), 1996. [CEA publication #706]
Much progress has been made toward our understanding of coronal
activity in late-type stars as the result of observations with
spaceborne instrumentation (UV, EUV, and X-rays). A general picture
has emerged that the most active stars are the fastest rotators. EUV
radiative losses are comparable to the X-ray losses and are important
in the energy balance of the corona (Mathioudakis et al. 1995). The
Extreme Ultraviolet Explorer (EUVE) 58 to 740 A bandpass is
particularly sensitive to the coronal emission.

OPTICAL COUNTERPARTS OF COMMON AND RARE EUVE DETECTIONS
N. Craig
To appear in Proceedings of the 9th Cambridge Workshop, Cool Stars,
Stellar Systems, and the Sun, ed. R. Pallavicini and A. K. Dupree,
PASP Conf. Ser. (San Francisco: ASP), 1996. [CEA publication #707]
The most recently published EUV source catalogs reveal the types of
objects observable in the EUV (Bowyer et al. 1996; Pounds et al.
1993). About 40% of the sources are late-type stars (G, K, and M
dwarfs and tidally interacting binaries) whose coronae have typical
temperatures of ~(1-10)E+6 K (e.g., Pallavicini 1989). The other ~27%
comprise primarily hot white dwarfs (WD), with a smaller number of
early-type stars, active galactic nuclei, planetary nebulae,
cataclysmic variables, X-ray binaries, one or two novae, and thermally
emitting neutron stars. The remaining ~33% of all sources are NOIDs
(sources without plausible optical counterparts).

DISCOVERY OF 0.5 MILLION K GAS IN THE CENTER OF GALAXY CLUSTERS
R. Lieu, J.P.D. Mittaz, S. Bowyer, F.J. Lockman, C.-Y. Hwang, and
J.H.M.M. Schmitt
To appear in Proceedings of the X-ray Meeting in Wurzburg. [CEA
publication #710]
An observation of M87, the central galaxy of the Virgo cluster, was
performed in the 0.065-0.245 keV energy band by the deep survey (DS)
telescope aboard the Extreme Ultraviolet Explorer (EUVE). A central
source and an extended emission halo of radius ~120 kpc are clearly
visible in the data and represent the first detection of cluster gas
emission in the EUV. The emission cannot be explained by the
well-known cluster gas at X-ray temperatures (Fabricant & Gorenstein
1983; Forman, Jones, & DeFaccio 1985; Stewart et al. 1984a; Bohringer
et al. 1994). Instead, it is necessary to introduce a second gas
component, with temperature between 5E+5 and 1E+6 K. The rapid
cooling of plasmas at such temperatures implies a mass accretion rate
of > 300 M_(solar) per yr. It is unlikely that the phenomenon is
directly related to a cooling flow, which involves a much lower rate
of ~10 M_(solar) per yr. More recently, we examined ROSAT PSPC data
of other galaxy clusters located in directions of low galactic
absorption, and found that all of them show evidence of extended
central emission at T ~ 1E+6 K. In particular, the Coma cluster,
which was also detected by the EUVE sky survey, exhibits soft emission
out to a radius of ~1 Mpc from the X-ray centroid, with an estimated
gas cooling (accretion) rate of ~2E+5 M_(solar) per yr. This result
is a major surprise, since Coma does not have a cooling flow.

THE EUVE KNOWLEDGE BASE
M. Abbott
To appear in proceeding of the Fifth Annual Conference on Astronomical
Data Analysis Software and Systems (ADASS '95), Oct. 22-25, 1995,
Tucson, AZ. [CEA publication #711]
The EUVE Knowledge Base (KB) will be an online repository of the
exper tise of the developers and users of the Extreme Ultraviolet
Explorer (EUVE) satellite and data analysis software. It will help to
address the issue of maintaining adequate support for Guest
Investigators after the project has entered a purely archival stage
with few or no personnel available to answer questions. It will also
help to preserve knowledge about EUVE as particular people may leave
the project. The KB will be accessible as a hypertext document in the
CEA WWW site. Information will be stored internally in small "units,"
and cross-references will be created between individual units
on-the-fly as they are delivered to users. This will enable us to
tailor the documents to allow each user to explore the KB as
efficiently as possible.

DEVELOPMENT AND DEPLOYMENT OF A RULE-BASED EXPERT SYSTEM FOR
AUTONOMOUS SATELLITE MONITORING
L. Wong, F. Kronberg, A. Hopkins, F. Machi, and P. Eastham
To appear in proceedings of the Fifth Annual Conference on
Astronomical Data Analysis Software and Systems (ADASS '95), Oct.
22-25, 1995, Tucson, AZ. [CEA publication #713]
In compliance with NASA administrator Daniel Goldin's call for
faster, cheaper, better NASA projects, the Center for EUV Astrophysics
(CEA) in cooperation with NASA Ames Research Center has developed and
deployed a partially autonomous satellite-telemetry monitoring system
to monitor the health of the Extreme Ultraviolet Explorer (EUVE)
payload. Originally, telemetry was monitored on a 24 hour basis by
human operators. Using RTworks, a software package from Talarian
Corporation, our development team has developed a rule-based, expert
system capable of detecting critical EUVE payload anomalies and
notifying an anomaly coordinator. This paper discusses the process of
capturing and codifying the knowledge of EUVE operations into rules
and how our rule-based system is applied in EUVE autonomous
operations.

A MULTI-MISSION ARCHIVE
E. Olson, F. Girouard, and A. Hopkins
To appear in proceedings of the Fifth Annual Conference on Astronomical Data
Analysis Software and Systems (ADASS '95), Oct. 22-25, 1995, Tucson,
AZ. [CEA publication #714]
The ability to store and access mission data is a critical element
of mission operations. The Center for EUV Astrophysics, which
operates the Extreme Ultraviolet Explorer (EUVE) Science Operations
Center for Goddard Space Flight Center, is currently developing the
Tomographic Experiment using Radiative Recombinative Ionospheric EUV
and Radio Sources (TERRIERS) ground system in collaboration with Ames
Research Center and AeroAstro for Boston University. CEA is designing
a general-purpose data archive for storing, indexing, and accessing
spacecraft telemetry. A specification file will describe the
mission-specific information about telemetry formats. By reusing
software components, as might be possible with the Multi-Mission
Archive, new missions will be able to focus their efforts on
instrumentation and analysis.

2.2 Public Data Release for 1 Feb 1996
--------------------------------------
by Dr. Nahide Craig, CEA Scientist, ISO User Support Team
The table below lists the GO observations that become public on 1
Feb 1996. For each entry is given the target name, the approximate
exposure time in ksec, the GMT start and end date(s) for the
observation, the spectral type of the target, and the data
identification code. All public data sets can be ordered from the
archive via WWW and electronic or postal mail (see addresses below).
Please be sure to include in your order the DataID(s) of interest.
Processed data sets are shipped on 8mm tape (or, if requested, on
CD-ROM) via postal mail.
The data rights policy for GO observations states that GOs have
proprietary rights to the data for one year from the date (s)he
receives it. It is often the case that long observations are broken
up over many months; e.g., an observation approved for 60 ksec may
actually be observed for 10 ksec one month, 20 ksec the next and 30
ksec three months later. In such cases the one-year proprietary
period begins after the GO is sent the final piece of the completed
observation.
