报告地点：理生楼B310

报告人简介：

   本科毕业于安徽师范大学物理学，硕士就读于广西大学、师从梁恩维教授从事伽马射线暴的数据统计分析工作。其后于2015-2019在瑞士日内瓦大学天文系从事双星演化的研究，期间主要研究黑洞的自转起源在不同的黑洞双星系统（双黑洞和大质量X-Ray 射线双星）中。于2019年9月赴美国西北大学天体物理做博士后。

报告摘要：

   In this talk, I will first give a short introduction of stellar evolution (including effects of rotation and in binaries), black hole (BH) study in two binary systems (double BH systems and high-mass X-ray binaries), as well as the spin of the BH. From the observational point of view, the BH spins in coalescing binary BHs seem to be in contradiction with the ones observed in high-mass X-ray binaries (HMXBs). Various double BH formation channels have been proposed since the first gravitational wave event GW150914 was detected. I will show that the currently observed 10 events can be explained by isolated binary evolution through common envelope channel. For 3 HMXBs with BH spin measurements
