标题： Gamma-Ray Bursts as the Death Throes of Massive Binary Stars

摘要： 有人提出，伽马射线暴是在宇宙距离上由双中子星 binaries 和黑洞中子星 binaries 合并产生的。 具有复杂轮廓和相对较长持续时间的暴发是由合并后差速旋转盘中的帕克不稳定引起的磁暴造成的。 一些暴发也可能是通过中微子-反中微子湮变为电子和正电子产生的。 在这两种情况下，最初会形成一个大小为$\sles\ 100$公里的光学厚火球，它会超相对论性地膨胀到大半径后再辐射。 有几个以前对宇宙合并模型的反对意见被消除了。 预计$\gamma$射线暴将伴随着从螺旋进入的双星系统发出的引力波爆发，这可能被LIGO探测到。 显示英文摘要

摘要： It is proposed that gamma-ray bursts are created in the mergers of double neutron star binaries and black hole neutron star binaries at cosmological distances. Bursts with complex profiles and relatively long durations are the result of magnetic flares generated by the Parker instability in a post-merger differentially-rotating disk. Some bursts may also be produced through neutrino-antineutrino annihilation into electrons and positrons. In both cases, an optically thick fireball of size $\sles\ 100$ km is initially created, which expands ultrarelativistically to large radii before radiating. Several previous objections to the cosmological merger model are eliminated. It is predicted that $\gamma$-ray bursts will be accompanied by a burst of gravitational radiation from the spiraling-in binary which could be detected by LIGO.
