Phase light curves for extrasolar Jupiters and Saturns

Ulyana A. Dyudina, Penny D. Sackett, Daniel D. R. Bayliss +4

We predict how a remote observer would see the brightness variations of giant planets similar to Jupiter and Saturn as they orbit their central stars. We model the geometry of Jupi…
