Eclipsing Binaries

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.

Data Columns

The following table describes the data column names of the eclipsing binary (centroid) information in the archive.

Column Name Description
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
ebff Fillout factor
(F = (Omega - Omega_L2)/(Omega_L1 -x Omega_L2), where Omega is the gravity potential)
