KEPLER_CP

Search results output columns:

Planet Name
Planet name in the form kepler-n[b,c,d..] where n is a sequential number followed by a letter (starting with b) to distinguish planets in multiple planetary systems.
example: kepler-7b

Kepler ID
Kepler ID identifying corresponding star entry in the Kepler Input Catalog. Note planets in the same star system are assigned the same Kepler ID.
range: 757450 to 12735740

KOI Name
Kepler assigned Object of Interest (KOI) name in the form KNNNNN.DD where NNNNN designates the host star and DD is a 2-digit number designating a transiting object. Note some planets have not been assigned a KOI name and some have KOI names which are no longer included in the current KOI list.
example: K00203.01

Alt Name
Additional name as provided by the planet discovery publication. This name is given for a confirmed planet not listed in the KOI candidate lists or lacking a KOI name.
example: KOI-55 c

KOI Number
The Kepler Object of Interest (KOI) number stored as a floating point number (i.e., not as a string). This field can be searched using numberical operators or for sorting output by KOI number.
range: 1.01 to 4745.01

RA (J2000)
Right Ascension in decimal degrees.
range: 280.69 to 301.72

2mass Name
2Mass designation
examples: 2MASS J19024305+5014286

Planet temp
Computed planet temperatures are based on an assumption that the planet is in equilibrium with radiation from its star balanced by its own black body radiation, taking into account some reflection of radiation from the planet (albedo). Actual albedo is unknown. The planet temperatures calculated do not take into account atmospheric properties, since these are unknown. If Earth did not have atmosphere, its temperature would be below the freezing point of water. In the case of Jupiter, not only does it have an atmosphere to complicate things, but a significant internal heat source as well.
range: 178 to 3961 degrees K

Planet Radius
Estimated planet radius (earth = 1.0)
range: 0.27 to 3791.05

Transit duration
Duration of transit
range: roughly 0.43 to 16.72

Period
Estimated Planet period in earth days
range: roughly 0.45 to 704.96

Period err1
Lower uncertainty limit in Planet period in earth days
range: roughly 0 to 0.011

Ingress Duration
The time between first and second contact of the planetary transit. Contact times are typically computed from a best-fit model produced by a Mandel-Agol (2002) model fit to a multi-quarter Kepler light curve, assuming a linear orbital ephemeris.
currently all null

Impact Parameter
The sky-projected distance between the center of the stellar disc and the center of the planet disc at conjunction, normalized by the stellar radius.
0 to 44.58

Inclination
The angle between the plane of the sky (perpendicular to the line of sight) and the orbital plane of the planet candidate.
39.53 to 89.95

Provenance
Provenance of stellar parameters. A flag describing the source of the stellar parameters.

KIC = the parameters are extracted from the Kepler Input Catalog (Brown et al. 2011). Uncertainties of Teff = 200 K, log(g) = 0.3 dex and [Fe/H] = 0.4. J-K = the star is unclassified in the KIC, J-K has been used to estimate temperature. The host star is assumed to be on the ZAMS with corresponding log(g) based on the Schmidt-Kaler relation.
Solar = the star is unclassified in the KIC, so the host star is assumed to have solar properties.
SME = Spectroscopic parameters derived from SME analysis (Valenti and Piskunov 1996). Stellar parameters are derived based on stellar evolution models.
SPC = Spectroscopic parameters derived from SPC analysis (Buchhave et al. 2012). Stellar parameters are derived based on stellar evolution models.
Pinsonneault = uses a revised Teff scale from Pinsonneault et al. (2012) with [Fe/H] fixed at -0.2. The quantity log(g) is taken from the KIC. Values are then revised by fitting to Yonsei-Yale stellar evolution models (Yi et al. 2001).
Astero = host star properties have been measured by comparison with astroseismologial models.

examples: SPC, Solar, SME, null, Pinsonneault, KIC, J-K

KEP Mag
A magnitude computed according to a hierarchical scheme and depends on what pre-existing catalog source is available, SCP, Tycho 2, or photographic photometry, in order of preferred selection. For SCP stars the magnitude is synthesized from the Sloan-like g and r magnitudes according to the following prescription: if one defines 'color' as g - r, then for color less than or equal to 0.8 kepmag = 0.8r + 0.2g, while for color greater than 0.8 kepmag = 0.9r + 0.1g. Empirical measurements for presumed constant stars suggest that the r.m.s. for this quantity is slightly larger 0.02 mags. except for very faint and bright stars.

KOI List
Designates entries included in Kepler Objects of Interest (KOI) catalog. Some entries not in KOI list may still have a KOI name if the star is in the KOI list but not the planet. Note in general, less metadata is available for the non-KOI planets.
