How Exoplanet Radio Transits Probe Magnetic Fields to Find Super Earths - Ep 35

Dive into Magnetohydrodynamic (MHD) simulations of the HD 189733 star-planet system in order to predict radio transit modulations of exoplanets. Learn how MHD simulations can model electromagnetic field interactions between local stars and exoplanet magnetospheres at varying planetary radii, and field intensities to generate synthetic radio images (10MHz-1GHz), EM field strength, viewing phase angles, and local star parameters.

Topics include: Alfven Wave Solar Atmosphere Model (AWSOM),ray tracing algorithm,Plasma Physics Absorption coefficient,imaging Modulated waves, spacebased instruments, Scar telescope mission, and future research with radio, EUV, and Xray transits to run algorithms on datasets to classify 1,000 Earth-sized planets within 50ly
