原中子星风、磁星诞生和伽马射线暴

Proto-Neutron Star Winds, Magnetar Birth, and Gamma-Ray Bursts

B. D. Metzger, T. A. Thompson, E. Quataert

摘要:

我们首先回顾了热中微子驱动的原中子星(PNS)风的理论。包括磁场和旋转的影响,然后,我们推导出的质量和能量损失从磁驱动的PNS风的相对论和非相对论外流,包括重要的多维考虑。通过这些简单的分析标度,我们认为具有毫秒旋转周期的原磁星在核心坍缩后几秒钟产生相对论风,其光度、时间尺度、质量负载和内部冲击效率有利于产生长持续时间的伽马射线暴。

英文摘要:

We begin by reviewing the theory of thermal, neutrino-driven proto-neutron star (PNS) winds. Including the effects of magnetic fields and rotation, we then derive the mass and energy loss from magnetically-driven PNS winds for both relativistic and non-relativistic outflows, including important multi-dimensional considerations. With these simple analytic scalings we argue that proto-magnetars born with ~ millisecond rotation periods produce relativistic winds just a few seconds after core collapse with luminosities, timescales, mass-loading, and internal shock efficiencies favorable for producing long-duration gamma-ray bursts.
