Conventional models of gamma‑ray bursts are inadequate, prompting consideration of optically thick, distant sources. The study tests whether optically thick neutron‑star models can generate very hard spectra when the source energy density matches that of a ~1 MeV thermal radiation field. The model confines a pure energy quantity E in a sphere at >1 MeV temperature and then lets it expand freely. Published in The Astrophysical Journal (Sept 1986), DOI 10.1086/184741.

Abstract To test the hypothesis that optically thick neutron-star models can produce very hard spectra if the energy density of the source is as high as it is in a thermal radiation field at a temperature of about 1 MeV, consideration is given to the fate of a quantity E of pure energy. This quantity is initially confined to a sphere in equilibrium at a temperature greater than 1 MeV and then allowed to expand freely. Given the shortcomings of conventional models, the possibility that burst sources could be optically thick and distant should not be dismissed.
