GRB 070610/雨燕J195509 .6+261406的余辉:使用火球模型的解释

Afterglow from GRB 070610/Swift J195509.6+261406: an explanation using the fireball model

Kong SiWei, Huang Yong-Feng

摘要:

GRB 070610,也被命名为雨燕J195509.6+261406,是一个特殊的银河系瞬变现象,在短时间尺度上的X射线和光学光变曲线都有显著的变化。一个可能的解释是GRB 070610/Swift J195509.6 + 261406是银河系中的软伽马射线中继器(SGR)。本文采用通常被认为是伽马射线暴(GRB)余辉标准模型的火球模型和能量注入假说解释了GRB 070610/Swift J195509.6 + 261406的X射线和光学余辉光变曲线。结果表明,该模型与观测值基本一致。

英文摘要:

GRB 070610, which is also named Swift J195509.6+261406, is a peculiar Galactic transient with significant variability on short timescales in both X-ray and optical light curves. One possible explanation is that GRB 070610/Swift J195509.6 + 261406 is a soft gamma-ray repeater (SGR) in our Galaxy. Here we use the fireball model which is usually recognized as the standard model of gamma-ray burst (GRB) afterglows, and the energy injection hypothesis to interpret the X-ray and optical afterglow light curves of GRB 070610/Swift J195509.6 + 261406. It is found that the model is generally consistent with observations.
