Analysis of Thermal Emissions of Exoplanets with Axially Symmetric Temperature Gradients

Abstract Here a new method of modeling the thermal emissions exoplanets is described, in which temperature gradient an exoplanet approximated by splitting it into N zones. First, we seek to determine how much this differs from simple dayside–nightside model used previous researchers and found that difference between -zone models greatest during primary transit exoplanet, for large gradients. Next, under what conditions EXONEST, Bayesian inference software package, able correctly generate synthetic light-curve data. EXONEST best data when mass known, added noise low, are compared ellipsoidal variations. Finally, was analyze photometric Kepler-41b Kepler-412b, dayside brightness temperatures were estimated be 2574 ± 59 2496 64 K, those nightside 860 316 874 333 K respectively. hottest zone both planets nearest terminator on exoplanet. This surprising result suggests better applied with little no heat recirculation.
