作为伽马射线暴源的引力坍缩

Gravitational collapse as the source of gamma-ray bursts

V. V. Sokolov

摘要:

如果$e^{-}e^{+}$对产生的阈值取决于光子动量之间的角度,并且如果$γ$射线正好在伽马射线暴(GRB)源中准直,则紧凑性问题的另一种解决方案是可能的。给出了描述伽玛暴能量释放$< 10^{49}$ erg的基本假设:如果所有长持续时间的伽玛暴都与核塌缩超新星(SNe)有物理联系,那么它就是超相对论火球的替代物。辐射压力的问题,以及如何产生的喷流帐户,即使是一个小的辐射场不对称性的紧凑型伽玛暴源的大小$\lesssim 10^8$厘米,和观测后果的紧凑型模型的伽玛暴被认为是。

英文摘要:

If the threshold for $e^{-}e^{+}$ pair production depends on an angle between photon momenta, and if the $γ$-rays are collimated right in gamma-ray burst (GRB) source then another solution of the compactness problem is possible. The list of basic assumptions of the scenario describing the GRB with energy release $< 10^{49}$ erg is adduced: the matter is about an alternative to the ultrarelativistic fireball if all long-duration GRBs are physically connected with core-collapse supernovae (SNe). The questions about radiation pressure and how the jet arises on account of even a small radiation field asymmetry in a compact GRB source of size $\lesssim 10^8$ cm, and observational consequences of the compact model of GRBs are considered.
