Abstract:
I will briefly review the first decade of studying subsolar mass objects, namely brown dwarfs and extrasolar giant planets, with emphasis on physics and chemistry of their atmospheres, their predicted spectra, and a comparison of theory with observations. On the side of extrasolar giant planets, I will emphasize recent observational highlights, namely planetary transits and first deduced spectra of extrasolar planets using secondary eclipses, together with our modeling results. On the brown dwarf side, I will concentrate on a recent concentrated effort to explain the observed spectra and colors in the transition between the newly introduced spectroscopic types L and T, and the role of uncertainties in the cloud formation physics.
