Evolutionary models for cool brown dwarfs and extrasolar giant planets. The case of HD 209458
- I. Baraffe, G. Chabrier, T. F. Allard, P. Hauschildt
- Physics, Geology
- 14 February 2003
We present evolutionary models for cool brown dwarfs and extra-solar giant planets. The models re- produce the main trends of observed methane dwarfs in near-IR color-magnitude diagrams. We also…
Evolutionary Models for Very Low-Mass Stars and Brown Dwarfs with Dusty Atmospheres
- G. Chabrier, I. Baraffe, F. Allard, P. Hauschildt
- Physics, Geology
- 29 May 2000
We present evolutionary calculations for very low-mass stars and brown dwarfs based on synthetic spectra and nongray atmosphere models which include dust formation and opacity, i.e., objects with…
New evolutionary models for pre-main sequence and main sequence low-mass stars down to the hydrogen-burning limit
- I. Baraffe, D. Homeier, F. Allard, G. Chabrier
- Physics
- 13 March 2015
We present new models for low-mass stars down to the hydrogen-burning limit that consistently couple atmosphere and interior structures, thereby superseding the widely used BCAH98 models. The new…
Evolutionary models for low-mass stars and brown dwarfs: uncertainties and limits at very young ages
- I. Baraffe, G. Chabrier, F. Allard, Hauschildt
- Physics, Geology
- 20 November 2001
We analyse pre-Main Sequence evolutionary tracks for low mass stars with masses $m \\le 1.4 \\msol$ based on the Baraffe et al. (1998) input physics. We also extend the recent Chabrier et al. (2000)…
Theory of Low-Mass Stars and Substellar Objects

- Physics, Geology
- 27 June 2000
▪ Abstract Since the discovery of the first bona-fide brown dwarfs and extra-solar planets in 1995, the field of low-mass stars and substellar objects has progressed considerably, both from theoret...
THE EVOLUTION OF CATACLYSMIC VARIABLES AS REVEALED BY THEIR DONOR STARS
- C. Knigge, I. Baraffe, J. Patterson
- Physics
- 11 February 2011
We present an attempt to reconstruct the complete evolutionary path followed by cataclysmic variables (CVs), based on the observed mass–radius relationship of their donor stars. Along the way, we…
Structure and evolution of super-Earth to super-Jupiter exoplanets - I. Heavy element enrichment in the interior
- I. Baraffe, G. Chabrier, T. Barman
- Physics, Geology
- 13 February 2008
Aims. We examine the uncertainties in current planetary models and quantify their impact on the planet cooling histories and massradius relationships. Methods. These uncertainties include (i) the…
Evolutionary models for solar metallicity low - mass stars: Mass - magnitude relationships and color - magnitude diagrams
- I. Baraffe, G. Chabrier, F. Allard, P. Hauschildt
- Physics
- 2 May 1998
We present evolutionary models for low mass stars from 0.075 to 1 M for solar-type metallicities (M/H)= 0 and -0.5. The calculations include the most recent interior physics and the latest generation…
The Substellar Mass Function in σ Orionis
We combine results from imaging searches for substellar objects in the σ Orionis cluster and follow-up photometric and spectroscopic observations to derive a census of the brown dwarf population in a…
Evolution of low-mass star and brown dwarf eclipsing binaries
- G. Chabrier, J. Gallardo, I. Baraffe
- Physics, Geology
- 12 July 2007
Context. We examine the evolution of low-mass star and brown dwarf eclipsing binaries. These objects are rapid rotators and are believed to shelter large magnetic fields. Aims. We suggest that…
