Disentangling the Effects of Temperature, Clouds, and Gravity on K I doublet in L dwarfs

Alexandra J. Baldelli, Genaro Suárez, Kelle L. Cruz +2

We investigate the effects of surface gravity, effective temperature, and cloudiness on the potassium doublet (\ion{K}{1}) at 1.17 μm in brown dwarf spectra. Using pseudo-Voigt pro…
