Stellar Parameters

Kepler-25c Stellar Parameters
a The Kepler system number is given in parentheses (e.g., 25 means Kepler-25).
b Contamination values come from the KIC except KOI-841 which includes the effects of the non-KIC star seen in high resolution imaging.
c Quoted uncertainties do not include systematic uncertainties due to stellar models. Values with no stated uncertainties are from KIC.

System Parameters

Kepler-25c System Parameters
a BJD-2454900
b From Borucki et al. (2011)
c Updated to reflect stellar properties from Stellar Parameters listed above
d Number of transit times measured in Q0-6
e Median absolute deviation from linear ephemeris measured during Q0-6
f Based on assumption of dynamical stability and stellar mass from Stellar Parameters listed above

Light Curve

Kepler-25c Light Curve
Phase-folded lightcurve (corrected for TTVs) for Kepler-25c. The period of the planet is 12.72 days for Kepler–25c. The excess scatter observed are due to anomalous, abrupt changes in reported flux being passed through the detrending algorithm.
