Ohmic Heating In The Upper Atmosphere of Hot Exoplanets The Influence of a Time-varying Magnetic Field
Exoplanets on close-in orbit are subject to intense X-ray and ultraviolet (XUV) irradiation from their star. Their atmosphere therefore heats up, sometimes to the point where it thermally escapes from […]
