摘要：
A common mechanism for both X-ray and gamma-ray bursters is proposed on the basis that a ''window'' can be created transiently in the polar cap of a degenerate star, a white dwarf for X-ray bursts and a neutron star for gamma-ray bursts. The ''window'' exposes transiently a hot degenerate sub-layer of the star at shallow depth, from which escapes blackbody flux for a source at temperature 3 kev with window radius 10 km in the case of X-ray bursts and for a source at temperature 300 kev with window radius 0.5 km in the case of gamma-ray bursts.
