MHD Study of Extreme Space Weather Conditions for Exoplanets With Earth‐Like Magnetospheres: On Habitability Conditions and Radio‐Emission

The present study aims at characterizing the habitability conditions of exoplanets with an Earth-like magnetosphere inside habitable zone M stars and F like tau Boo, caused by direct deposition stellar wind on exoplanet surface if shielding is inefficient. In addition, radio emission generated a calculated for different space weather conditions. based set MHD simulations performed code PLUTO reproducing expected orbiting type Boo. Exoplanets hosted 0.2 au are protected from during regular CME-like star rotation period slower than 3 days, that to say, faster rotators generate winds interplanetary magnetic fields large enough endanger habitability. Boo >= 2.5 conditions, but stronger field compared Earth mandatory close inner edge (2.5 au) shield range values in consistent scaling proposed [Zarka 2018] common If telescopes measure relative low signal small variability exoplanet, may indicate favorable respect states considered intrinsic exoplanet.
