Abstract
We present the results of our long-term photometric and spectroscopic monitoring with the 1.5-m telescope RTT-150 for the optical counterpart of the high-mass X-ray binary IGR J21343+4738 discovered in 2002 by the INTEGRAL space X-ray observatory. The X-ray source was also repeatedly detected by the telescopes of the SRG observatory during the all-sky surveys in the period 2019–2021. We have investigated the spectroscopic and photometric variabilities of the optical counterpart, a Be star, caused by physical processes in the equatorial disk. The evolution of the equatorial disk parameters over a long time interval of 16 years has been analyzed.
摘要我们介绍了利用 1.5 米望远镜 RTT-150 对 INTEGRAL 空间 X 射线天文台 2002 年发现的高质 X 射线双星 IGR J21343+4738 的光学对应体进行长期光度和光谱监测的结果。在 2019-2021 年期间的全天空巡天中，SRG 天文台的望远镜也多次探测到该 X 射线源。我们研究了由赤道盘物理过程引起的光学对应星（一颗 Be 星）的光谱和光度变化。我们分析了长达 16 年的赤道圆盘参数演变过程。
