Structure and evolution of super-Earth to super-Jupiter exoplanets: I. heavy element enrichment in the interior
I. Baraffe, G. Chabrier, T. Barman
We examine the uncertainties in current planetary models and we quantify their impact on the planet cooling histories and mass-radius relationships. These uncertainties include (i)…
Fundamental properties of low-mass stars
I. Ribas, J. Morales, C. Jordi +3
Numerous investigations on the fundamental properties of low-mass stars using eclipsing binaries indicate a strong discrepancy between theory and observations that is still awaitin…
Eight new T4.5-T7.5 dwarfs discovered in the UKIDSS Large Area Survey Data Release 1
N. Lodieu, D. J. Pinfield, S. K. Leggett +4
We present eight new T4.5-T7.5 dwarfs identified in the UKIRT Infrared Deep Sky Survey (UKIDSS) Large Area Survey (LAS) Data Release 1 (DR1). In addition we have recovered the T4.5…
The glow of primordial remnants
Gilles Chabrier
We determine the expected surface brightness and photometric signature of a white dwarf remnant population, issued from primordial low-mass stars formed at high redshifts, in today…
The physics of extrasolar gaseous planets : from theory to observable signatures
G. Chabrier, F. Allard, I. Baraffe +2
We review our present understanding of the physical properties of substellar objects, brown dwarfs and irradiated or non-irradiated gaseous exoplanets. This includes a description…
The Galactic disk mass-budget : II. Brown dwarf mass-function and density
G. Chabrier
In this paper, we extend the calculations conducted previously in the stellar regime to determine the brown dwarf IMF in the Galactic disk. We perform Monte Carlo calculations taki…
