Abstract
Main sequence M stars are the most abundant stars in our galaxy, they have features that make them an attractive target for Astrobiology, but their strong chromospheric activity produces high energy radiation and charged particles that may be detrimental to life. We study the impact of a strong flare from the M dwarf, AD Leo, on the atmospheric chemistry of a hypothetical Earth-like planet located in the habitable zone. The simulations were performed using a 1-D photochemical model. We simulated
