Model X-ray spectra of magnetic neutron stars with hydrogen atmospheres

Ho, Wynn C.G., Potekhin, Alexander Y. and Chabrier, Gilles (2008) Model X-ray spectra of magnetic neutron stars with hydrogen atmospheres The Astrophysical Journal Supplement Series, 178, (1), pp. 102-109. (doi:10.1086/589238).

Record type: Article


We construct partially ionized hydrogen atmosphere models for magnetized neutron stars in radiative equilibrium with fixed surface fields between B = 1012 and 2 × 1013 G and effective temperatures log Teff = 5.5–6.8, as well as with surface B and Teff distributions around these values. The models are based on the latest equation of state and opacity results for magnetized partially ionized hydrogen plasmas. The atmospheres directly determine the characteristics of thermal emission from the surface of neutron stars. We also incorporate these model spectra into XSPEC, under the model name NSMAX, thus allowing them to be used by the community to fit X-ray observations of neutron stars.
