HAT P 7b light curve
HAT P 7b light curve
Upper: Detrended and phase-folded light curve at 1-min cadence along with the Eclipsing Light Curve fit.
Lower: Light curve averaged in 5 min and 75 min bins. The double-humped shape is due to the ellipsoidal variations of the star plus light from the planet.
