This model interpolates from a grid of NS atmosphere calculations provided by George Rybicki and Ramesh Narayan to output a NS atmosphere spectrum. The model grids cover a wide range of surface gravity and effective temperature, and incorporate thermal electron conduction and self-irradiation by photons from the compact object. This code assumes negligible (less than G) magnetic fields and a pure hydrogen atmosphere. A detailed description of the model is given in Heinke et al. (2006) (see also McClintock et al. 2004).
par1 | : (unredshifted) effective temperature |
par2 | : neutron star gravitational mass (in units of Solar mass) |
par3 | : “true” neutron star radius (km) |
par4 | dist : distance to the neutron star (in kpc) |
norm | fraction of the neutron star surface emitting |
