System Parameters for Kepler 8b

8b data table

A: Based primarily on the photometry.
B: Based on the photometry and radial velocities.
C: Based on spectrum analysis (FIES/MOOG or HIRES/SME).
D: Based on the Yale-Yonsei evolution tracks.
E: Based on Newton’s version of Kepler’s Third Law.
F: Assumes Bond albedo = 0.1 and complete redistribution.

Kepler 8b light curve
The detrended light curve for Kepler-8. The time series for the entire Kepler photometric data set is plotted in the upper panel. The lower panel shows the photometry folded by the period P = 3:52254 days, and the model fit to the primary transit is plotted as a solid line. Data for even and for odd transits are denoted by '+'s and '*'s, respectively. The even and odd transits do not exhibit significant variations in transit depth indicative of the primary and secondary eclipses of an eclipsing binary. The photometry at the predicted time of occultation of the planet is shown just above the phased transit curve, showing no significant dimming at the level of 0.1 mmag. The lack of any dimming at the predicted time of occultation, along with the absence of both Astrometric motion in and out of transit and the absence of detected stellar companions, leaves the planetary interpretation as the only plausible model, confirmed by the Rossiter-McLaughlin detection.
