Dust in the Photospheric Environment II. Effect on the Near Infrared Spectra of L and T Dwarfs
Takashi Tsuji, Tadashi Nakajima, Kenshi Yanagisawa
We report an attempt to interpret the spectra of L and T dwarfs with the use of the Unified Cloudy Model (UCM). For this purpose, we extend the grid of the UCMs to the cases of log…
