摘要:

我们提出的结果分析伽玛暴101023在火壳方案。由于缺乏光学波段的数据,它的红移还没有确定,所以我们试图从阿马蒂关系式推断它,得到z=0.9。它的光变曲线呈现出双重发射,这使得它与已经研究过的GRB 091018非常相似。我们使用不同的光谱模型与XSPEC进行了时间分辨光谱分析,并用数字代码GRBsim拟合光变曲线。我们使用费米GBM数据来建立光变曲线,特别是第二个INa探测器,在范围(8-440 keV)。我们发现,第一次发射不符合GRB的要求,而第二部分完全符合规范GRB,P-GRB持续4秒。

英文摘要:

We present the results of the analysis of GRB 101023 in the fireshell scenario. Its redshift has not been determined due to the lack of data in the optical band, so we tried to infer it from the Amati Relation, obtaining z=0.9. Its light curve presents a double emission, which makes it very similar to the already studied GRB 091018. We performed a time-resolved spectral analysis with XSPEC using different spectral models, and fitted the light curve with the numerical code GRBsim. We used Fermi GBM data to build the light curve, in particular the second INa detector, in the range (8-440 keV). We found that the first emission does not match the requirements for a GRB, while the second part perfectly agrees with being a canonical GRB, with a P-GRB lasting 4s.
