摘要

摘要我们介绍了对超亮 X 射线源 VII Zw 403 ULX（UGC 6456 ULX）的一系列 X 射线观测、光度测量和光谱监测的分析结果。根据一些间接迹象，我们推测这个双星系统中的吸积器是一颗中子星。通过在来自超临界吸积盘的风的模型框架内分析这颗ULX在其活跃状态下的观测光谱，我们估计其质量流出率为（{}^{-1}/4.0/times 10^{-5}M_{\odot}\) yr\({}^{-1}\).

Investigation of the Ultraluminous X-ray Source VII Zw 403 ULX in the X-ray and Optical Ranges

We present the results of our analysis of the series of X-ray observations, photometric and spectroscopic monitoring for the ultraluminous X-ray source VII Zw 403 ULX (UGC 6456 ULX). Based on a number of indirect signs, we hypothesize that the accretor in this binary system is a neutron star. By analyzing the observed spectrum of this ULX taken during its active state within the framework of the model of a wind coming from the supercritical accretion disk, we have estimated the mass outflow rate to be \({\approx}4.0\times 10^{-5}M_{\odot}\) yr\({}^{-1}\).
