David L. Kaplan, Philip Chang, Matthew Van Adelsberg, Er Y. Potekhin
Seven candidate isolated, cooling neutron stars (INSs) have been identified by the ROSAT All-Sky Survey, of which the two brightest are RX J1856.5−3754 and RX J0720.4−3125 (see Treves et al.
Radiation from condensed surface of magnetic neutron stars (2008)
Matthew Van Adelsberg, Dong Lai, Er Y. Potekhin
Abstract Recent observations show that thermal X-ray spectra of many isolated neutron stars are featureless and in some cases well fit by a blackbody. Such perfect blackbody spectra are puzzling as...
MODELING SPECTRAL FEATURES FROM ISOLATED NEUTRON STARS (2008)
Dong Lai, Er Y. Potekhin, Gilles Chabrier
Abstract We study several effects that influence the strength of the proton cyclotron and atomic features in the thermal spectra of magnetic neutron stars. Magnetic field variations over the neutron...

Abstract RX J1856.5–3754 is one of the brightest nearby isolated neutron stars, and considerable observational resources have been devoted to it. However, current models are unable to...

The internal properties of the neutron star crust can be probed by observing the epoch of thermal relaxation. After the supernova explosion, powerful neutrino emission quickly cools the stellar core,...
Cooling Neutron Stars With Accreted Envelopes (2007)
Gilles Chabrier, Er Y. Potekhin, Dmitry G. Yakovlev
The relationships between the effective surface temperature T eff and internal temperature T b of nonmagnetized neutron stars with and without accreted envelopes are calculated for T eff ? 5 \Theta...
Atmospheres Of Magnetized Neutron Stars: (2007)
Vacuum Polarization And, Dong Lai, Er Y. Potekhin, Gilles Chabrier
We construct hydrogen atmosphere models for magnetized neutron stars in radiative equilibrium with surface elds B = 10 510 G and eective temperatures T e a few10 K by solving the full radiative...
Statistical equilibrium and ion cyclotron absorption/emission in strongly magnetized plasmas (2007)
Cyclotron lines are a powerful diagnostic tool for magnetized neutron stars. The detection of electron cyclotron features at 10–80 keV in the spectra of a number of binary X-ray pulsars (e.g....
MAGNETIC FIELDS AND NEUTRON STAR ATMOSPHERE MODELS (2004)
Er Y. Potekhin, Dong Lai, Gilles Chabrier
The polarizability tensor of a strongly magnetized plasma and the polarization vectors and opacities of normal electromagnetic waves are studied for conditions typical of neutron star atmospheres,...

Recent observations show that the thermal X-ray spectra of many isolated neutron stars are featureless and in some cases (e.g., RX J1856.5 3754) well fit by a blackbody. Such a perfect blackbody...
