Toward A Self Consistent MHD Model of Chromospheres and Winds From Late Type Evolved Stars

Autor: Airapetian, V. S., Leake, J. E., Carpenter, K. G.

We present the first magnetohydrodynamic model of the stellar chromospheric heating and acceleration of the outer atmospheres of cool evolved stars, using alpha Tau as a case study. We used a 1.5D MHD code with a generalized Ohm's law that accounts f

Over 300 extrasolar planets (exoplanets) have been detected orbiting nearby stars. We now hope to conduct a census of all planets around nearby stars and to characterize their atmospheres and surfaces with spectroscopy. Rocky planets within their sta
