THE INTRINSIC EXTREME ULTRAVIOLET FLUXES OF F5 V TO M5 V STARS
THE INTRINSIC EXTREME ULTRAVIOLET FLUXES OF F5 V TO M5 V STARS
Extreme ultraviolet (EUV) radiations (10--117 nm) from host stars play important roles in the ionization, heating, and mass loss from exoplanet atmospheres. Together with the host star's Lyman-alpha and far-UV (117--170 nm) radiation, EUV radiation photodissociates important molecules, thereby changing the chemistry in exoplanet atmospheres. Since stellar EUV fluxes cannot …
