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
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
Atomic and Molecular Opacities for Brown Dwarf and Giant Planet Atmospheres
We present a comprehensive description of the theory and practice of opacity calculations from the infrared to the ultraviolet needed to generate models of the atmospheres of brown dwarfs andExpand
The Near-Infrared and Optical Spectra of Methane Dwarfs and Brown Dwarfs
We identify the pressure-broadened red wings of the saturated potassium resonance lines at 7700 A as the source of anomalous absorption seen in the near-infrared spectra of Gliese 229B and, byExpand
Line Intensities and Molecular Opacities of the FeH F 4?i-X 4?i Transition
We calculate new line lists and opacities for the F 4 Di-X 4 Di transition of FeH. The 0-0 band of this transition is responsible for the Wing-Ford band seen in M-type stars, sunspots, and brownExpand
New CrH Opacities for the Study of L and Brown Dwarf Atmospheres
In this paper, we calculate new line lists and opacities for the 12 bands of the A 6þ X 6þ transitions of the CrH molecule. Identified in objects of the new L dwarf spectroscopic class (many of whichExpand
Sulfur chemistry with time-varying oxygen abundance during Solar System formation
Chemical models of solar nebula chemistry are presented which show the influence of progressive water depletion from the inner solar nebula. The main focus of this work is the equilibriumExpand
Spectroscopic constants, abundances, and opacities of the TiH molecule
Using previous measurements and quantum chemical calculations to derive the molecular properties of the TiH molecule, we obtain new values for its rovibrational constants, thermochemical data,Expand
Molecular equilibrium with condensation. [in astrophysics]
Minimization of the Gibbs energy of formation for species of chemical elements and compounds in their gas and condensed phases determines their relative abundances in a mixture in chemicalExpand
Molecular equilibria and condensation temperatures in carbon-rich gases
Detailed chemical equilibrium calculations were carried out using a number of different C/O ratios, in order to determine the relative condensation sequence of various phases. For C/O > 1, weExpand
