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.   Constraining axion-like-particles with hard X-ray emission from magnetars 期刊论文 Journal of High Energy Physics, 2018, 卷号:  2018 作者:  Sinha, Kuver;  Fortin, Jean-François 收藏  |  浏览/下载：23/0  |  提交时间：2019/07/12 Cosmology of Theories beyond the SM  Beyond Standard Model  CP  violation  High Energy Physics - Phenomenology  Astrophysics - High  Energy Astrophysical Phenomena   A low-latency pipeline for GRB light curve and spectrum using Fermi/GBM near real-time data 期刊论文 Research in Astronomy and Astrophysics, 2018, 卷号:  18 作者:  Shao, Jian-Xiong;  Li, Han-Cheng;  Bu, Qing-Cui;  Feng, Min-Zi;  Li, Zheng-Heng 收藏  |  浏览/下载：45/0  |  提交时间：2019/07/12 Astrophysics - Instrumentation and Methods for Astrophysics  Astrophysics - High Energy Astrophysical Phenomena   The GeV emission of PSR B1259-63 during its last three periastron passages observed by Fermi-LAT 期刊论文 Research in Astronomy and Astrophysics, 2018, 卷号:  18 作者:  Zhang, Shu;  Chen, Yu-Peng;  Kong, Ling-Da;  Ji, Long;  Liu, Cong-Zhan 收藏  |  浏览/下载：19/0  |  提交时间：2019/07/12 Astrophysics - High Energy Astrophysical Phenomena   laboratorystudyofastrophysicalcollisionlessshockatsgiilaserfacility 期刊论文 highpowerlaserscienceandengineering, 2018, 卷号: 6, 期号: 3 作者:  Yuan Dawei;  Wei Huigang;  Liang Guiyun;  Wang Feilu;  Li Yutong 收藏  |  浏览/下载：3/0  |  提交时间：2020/03/11
