Modeling Brown Dwarfs, L Dwarfs, and T Dwarfs

Abstract

In this contribution, I review a subset of our recent efforts in spectral and opacity modeling aimed at guiding the study of brown dwarfs, L dwarfs, and T dwarfs. I discuss theoretical calculations of the alkali line profiles, newly generated CrH opacities, new evidence for refractory rainout in T dwarfs from optical spectral measurements, and the controversy concerning the distinction between brown dwarfs and planets.
