Magnetism in hot Jupiter Atmospheres

Wednesday, August 6, 2014

Magnetism has been proposed as a panacea for many unexplained observations of hot Jupiters, such as their  inflated radii and variability in day-night temperature variation.  Yet, until now, no self-consistent magnetohydrodynamic (MHD) simulations had been conducted.  In this talk I will present the first self-consistent MHD simulations of hot Jupiter atmospheres and describe the Ohmic heating and inflation that results and the effect magnetism has on hot Jupiter winds.  I will discuss how these results differ from previous approximations and describe some observational tests of the predictions.
