System Notice: The NASA Exoplanet Archive will be unavailable
on Tuesday, March 11 from 10-10:30am PDT.
The Kepler eclipsing binary catalog was compiled by members of the Kepler science team, both as a reference for groups interested in eclisping binaries, and as part of understanding the false-positive statistics for planet detection. The NASA Exoplanet Archive includes eclipsing binary information only for those stars identified as such.
The following table describes the data column names of the eclipsing binary (centroid) information in the archive.
|kepid||Kepler unique identification number|
|ebid||Unique eclipsing binary identifier|
|ebtype||Designation of the morphology type:|
D = detached
SD = semi-detached
OC = overcontact
ELV = ellipsoidal
? = uncertain
|ebepoch||Epoch of eclipse (BKJD = BJD - 2454833.0)|
|ebperiod||Transit period of system (days)|
|ebteffr||Ratio of Effective Temperature of stars in the system|
|ebfracsrad||Sum of fractional stellar radii|
|ebmassr||Ratio of stellar mass|
|ebesinw||radial component of eccentricity (e sin(omega)) component fit|
|ebecosw||tangential component of eccentricity (e cos(omega)) component fit|
|ebsini||Sine of orbital inclination|
(F = (Omega - Omega_L2)/(Omega_L1 -x Omega_L2), where Omega is the gravity potential)
