We summarize and extend recent work on the theory of extrasolar giant planets (EGPs) and brown dwarfs, paying particular attention to Gliese 229 B, the albedos of EGPs, the compositions of substellar atmospheres, the connections with the giant planets in the solar system, cloud physics, and non-gray spectral synthesis. The role of condensates in altering the optical spectrum of Gliese 229 B is explored, as are the systematics of the reflection spectra from extrasolar giant planets near their… Expand

Chemistry of Low Mass Substellar Objects
“Brown dwarfs” is the collective name for objects more massive than giant planets such as Jupiter but less massive than M dwarf stars. This review gives a brief description of the classification andExpand

Microlensing search for extra solar planets
Gravitational microlensing may be used to probe distant stars for planetary companions. The presence of a planet in the vicinity of a star acting as the lens may cause a short lived anomaly in theExpand
The Deuterium-burning Mass Limit for Brown Dwarfs and Giant Planets
There is no universally acknowledged criterion to distinguish brown dwarfs from planets. Numerous studies have used or suggested a definition based on an object’s mass, taking the �13-Jupiter massExpand

A Nongray Theory of Extrasolar Giant Planets and Brown Dwarfs
We present the results of a new series of nongray calculations of the atmospheres, spectra, colors, and evolution of extrasolar giant planets (EGPs) and brown dwarfs for effective temperatures belowExpand
A Theory of Extrasolar Giant Planets
We present a broad suite of models of extrasolar giant planets (EGP's), ranging in mass from 0.3 to 15 Jupiter masses. The models predict luminosity (both reflected and emitted) as a function of age,Expand
Atmospheric, Evolutionary, and Spectral Models of the Brown Dwarf Gliese 229 B
TLDR
Model results confirm the existence of methane and water in the spectrum of Gliese 229 B and indicate that its mass is 30 to 55 jovian masses, meant to guide future searches for extrasolar giant planets and brown dwarfs. Expand
The dusty atmosphere of the brown dwarf Gliese 229B.
TLDR
Gliese 229B's 0.85- to 1.0-micrometer spectrum indicates particulates deep in the atmosphere having optical properties of neither ice nor silicates, which suggests an organic composition characteristic of aerosols in planetary stratospheres. Expand
Chemical Equilibrium Abundances in Brown Dwarf and Extrasolar Giant Planet Atmospheres
We explore detailed chemical equilibrium abundance profiles for a variety of brown dwarf and extrasolar giant planet atmosphere models, focusing in particular on Gl 229B, and derive the systematicsExpand
