Far-ultraviolet Activity Levels of F, G, K, and M Dwarf Exoplanet Host Stars
Far-ultraviolet Activity Levels of F, G, K, and M Dwarf Exoplanet Host Stars
We present a survey of far-ultraviolet (FUV; 1150 - 1450 Ang) emission line spectra from 71 planet-hosting and 33 non-planet-hosting F, G, K, and M dwarfs with the goals of characterizing their range of FUV activity levels, calibrating the FUV activity level to the 90 - 360 Ang extreme-ultraviolet (EUV) …
