Equation of state and opacities for hydrogen atmospheres of magnetars
A. Y. Potekhin, G. Chabrier
The equation of state and radiative opacities of partially ionized, strongly magnetized hydrogen plasmas, presented in a previous paper [ApJ 585, 955 (2003), astro-ph/0212062] for…
Atmospheres and Spectra of Strongly Magnetized Neutron Stars -- III. Partially Ionized Hydrogen Models
Wynn C. G. Ho, Dong Lai, Alexander Y. Potekhin +1
We construct partially ionized hydrogen atmosphere models for magnetized neutron stars in radiative equilibrium with surface fields B=10^12-5 \times 10^14 G and effective temperatu…
Galactic Stellar and Substellar Initial Mass Function
Gilles Chabrier
We review recent determinations of the present day and initial mass functions in various components of the Galaxy, disk, spheroid, young and globular clusters. As a general feature…
Evolutionary models for cool brown dwarfs and extrasolar giant planets. The case of HD 20945
I. Baraffe, G. Chabrier, T. Barman +2
We present evolutionary models for cool brown dwarfs and extra-solar giant planets. The models reproduce the main trends of observed methane dwarfs in near-IR color-magnitude diagr…
