The parameters are: the terminal velocity of the wind, the mass loss rate of the donor, the effective temperature and the magnetic fields. These parameters influence significantly the improvement of the model of accretion. In spite of the variety of their observational properties, the corresponding magnetic field is around B ~ 10^12 G. This result can be constrained by the effects on stellar evolution. In addition, we have performed a segmentation in the parameter space of donors intended for several SG-HMXB listed in our sample set. The parameter space can be categorized into five regimes depending on the possibility of disk formation associated with accretion from the stellar wind. This can give a quantitative clarification of the observed variability and the properties of these objects. We show that, when these systems come into the direct accretion region, systems with corresponding parameters can emit X-rays.   Calvera: A Low-mass Strangeon Star Torqued by Debris Disk? 期刊论文 ASTROPHYSICAL JOURNAL, 2018, 卷号: 854, 期号: 2, 页码: 165 作者:  Ge MY(葛明玉);  Wang, WY;  Li, YY;  Xu, RX;  Tong, H 收藏  |  浏览/下载：21/0  |  提交时间：2019/09/24 accretion, accretion disks  pulsars: individual (Calvera1RXS J141256.0+792204)  stars: neutron   Star-Disk Interactions in Multiband Photometric Monitoring of the Classical T Tauri Star GI Tau 期刊论文 ASTROPHYSICAL JOURNAL, 2018, 卷号: 852, 期号: 1, 页码: 56 作者:  Michel, Raul;  Chiang, Po-Shih;  Fu, Jianning;  Jose, Jessy;  Herczeg, Gregory J. 收藏  |  浏览/下载：58/0  |  提交时间：2018/08/29 Stars: Pre-main Sequence  Stars: Variables: t Tauri  Herbig Ae/be
