论文摘要
风馈超级X射线二进制文件是宝贵的实验室，不仅是在极端重力和磁场条件下研究吸积，而且还探究了大规模恒星风的高度争议性能。其中包括所谓的团块，源自线驱动风的固有不稳定和较大的结构。在本文中，我们报告了我们小组自2007年以来与XMM-Newton和Swift Neil Gehrels天文台进行的最后一次（但尚未发布）监视运动的结果。使用史诗般的摄像机在板载XMM-Newton收集的数据使我们能够进行详细的硬度比率分辨光谱分析，可以用作检测与团块存在相关的光谱变化的有效方法。用XRT在板载迅速进行的长期观察，均匀地对许多不同轨道循环上超级X射线二进制的X射线发射，以寻找在紧凑型物体周围介质中的大型结构的存在。本文报道的结果代表了我们在超级X射线二进制4U 1907+09，IGR J16393-4643，IGR J19140+0951和XTE J1855-026，以及超级X-RAY的超级X-RAY J1733的结果IGR J19140+095133 33 33 33 33 33 33 333333的结果X-33 33 33 3333333333333333333333333 J18410-0535和IGR J11215-5952。所有结果均在风馈超级X射线二进制文件的背景下进行讨论，理想情况下应最佳地塑造针对同一类来源的下一个观察活动。我们在其中一篇论文附录中表明，在文献中将IGR J17315-3221归类为本文中可能由Integrales发现的超级X射线二进制的可能的超级X射线二元，是数据分析文物的产物，因此应被忽视以进行未来的研究。
Wind-fed supergiant X-ray binaries are precious laboratories not only to study accretion under extreme gravity and magnetic field conditions, but also to probe still highly debated properties of massive star winds. These includes the so-called clumps, originated from the inherent instability of line driven winds, and larger structures. In this paper, we report on the results of the last (and not yet published) monitoring campaigns that our group has been carrying out since 2007 with both XMM-Newton and the Swift Neil Gehrels observatory. Data collected with the EPIC cameras on-board XMM-Newton allow us to carry out a detailed hardness ratio-resolved spectral analysis that can be used as an efficient way to detect spectral variations associated to the presence of clumps. Long-term observations with the XRT on-board Swift, evenly sampling the X-ray emission of supergiant X-ray binaries over many different orbital cycles, are exploited to look for the presence of large scale structures in the medium surrounding the compact objects. The results reported in this paper represent the outcomes of the concluded observational campaigns we carried out on the supergiant X-ray binaries 4U 1907+09, IGR J16393-4643, IGR J19140+0951, and XTE J1855-026, as well as the supergiant fast X-ray transients IGR J17503-2636, IGR J18410-0535, and IGR J11215-5952. All results are discussed in the context of wind-fed supergiant X-ray binaries and shall ideally serve to optimally shape the next observational campaigns aimed at sources in the same classes. We show in one of the paper appendices that IGR J17315-3221, preliminary classified in the literature as a possible supergiant X-ray binary discovered by INTEGRAL, is the product of a data analysis artifact and should thus be disregarded for future studies.
