银河系X射线双星和eRosita的星族

Population of the Galactic X-ray binaries and eRosita

V. Doroshenko, L. Ducci, A. Santangelo, M. Sasaki

摘要:

到目前为止,银河系X射线双星的数量大多是用中等灵敏度的硬X射线测量来探测的。eRosita飞行任务将首次提供2-10千电子伏能量范围内的全天空灵敏X射线测量,X射线双星在该能量范围内发射大部分通量,并发现这些天体中尚未观测到的低光度群体。在本文中,我们简要地回顾了目前的限制X射线光度函数的高质量和低质量的X射线双星,并提出了我们自己的分析的基础上的INTEGRAL 9年银河系巡天,这产生了改进的限制。根据这些结果,我们估计了eRosita全天空调查中要检测到的新XRB的数量

英文摘要:

The population of the Galactic X-ray binaries has been mostly probed with moderately sensitive hard X-ray surveys so far. The eRosita mission will provide, for the first time a sensitive all-sky X-ray survey in the 2-10 keV energy range, where the X-ray binaries emit most of the flux and discover the still unobserved low-luminosity population of these objects. In this paper, we briefly review the current constraints for the X-ray luminosity functions of high- and low-mass X-ray binaries and present our own analysis based the INTEGRAL 9-year Galactic survey, which yields improved constraints. Based on these results, we estimate the number of new XRBs to be detected in the eRosita all-sky survey
