TL;DR: High-contrast observations with the Keck and Gemini telescopes have revealed three planets orbiting the star HR 8799, with projected separations of 24, 38, and 68 astronomical units.
Journal ArticleDOI
Evolutionary models for cool brown dwarfs and extrasolar giant planets. The case of HD 209458
TL;DR: In this article, the authors present evolutionary models for cool brown dwarfs and extra-solar giant planets and show that irradiation effects can substantially affect the radius of sub-jovian mass giant planets.
Journal ArticleDOI
Evolutionary models for cool brown dwarfs and extrasolar giant planets. The case of HD 20945
TL;DR: In this article, the authors present evolutionary models for cool brown dwarfs and extra-solar giant planets and show that irradiation effects can substantially affect the radius of sub-jovian mass giant planets.

TL;DR: In this paper, the authors presented a new table for low-temperature Rosseland and Planck mean opacities from Alexander & Ferguson, which includes more grain species and updated optical constants.
Journal ArticleDOI
Clouds and Chemistry in the Atmosphere of Extrasolar Planet HR8799b
TL;DR: In this paper, broad near-infrared H and K-band spectra of the young exoplanet HR8799b have been obtained using the integral field spectrograph OSIRIS, on the Keck II telescope.
