Event Details & Abstract: 

I will discuss the evolution of exoplanets close to their parent star. At such close separations high energy radiation from the star can heat the upper atmospheres of planets to temperatures high enough to drive a thermal wind. I will discuss the HD and MHD of the resulting flows. I will then consider the role evaporation plays in the evolution of exoplanets and argue that the low-mass, close-in exolplanet population detected by Kepler is sculpted by evaporation.
