Modeling neutron star thermal X-ray spectra with atmosphere models (hydrogen, helium, or carbon composition; isotropic or hot-spot geometries) to infer effective temperature, radius, and surface composition. Claims fitting or comparing such models to observed spectra belong here; pure blackbody fits without atmosphere assumptions do not.

Phase-averaged X-ray spectra alone cannot discriminate between carbon-atmosphere and hydrogen hot-spot models of central compact objects
