Kepler-4b

System Parameters for Kepler-4b
4b data table


Notes:
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 4b light curve
The phased light curve of Kepler-4b containing 13 transits observed by the Kepler photometer between 1 May 2009 and 15 Jun 2009. The upper panel shows the full 44-day time series after detrending. The bottom panel shows the light curve folded with the orbital period; different plot symbols denote odd- and even-numbered transits. The lower curve shows transit data over plotted on the fitted transit model. The upper curve covers the expected time of occultation, with the fitted (essentially constant) model overplotted. This model assumes a circular orbit. The full folded light curve (not shown here) gives no evidence for an occultation at any phase.
