Atmosphere Models for Very Low Mass Stars, Brown Dwarfs and Exoplanets

Abstract

Over the past decade considerable effort, both observational and theoretical, has been directed towards a more accurate determination of the stellar lower main sequence and of the sub-stellar domain covered by Brown Dwarfs and Planets. A review of the recent improvement in the theory of cool model atmospheres is presented.
