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…

Time-Varying Spectrum of the Random String
Lorenzo Galleani, Leon Cohen
We consider the response of a finite string to white noise and obtain the exact time-dependent spectrum. The complete exact solution is obtained, that is, both the transient and st…
