摘要:

X射线双星系统是天体物理研究中非常受欢迎的天体。这些系统中的致密天体是中子星、白矮星和黑洞。中子星和白矮星可以有内在的磁场。关于黑洞不存在内禀磁场,有一个众所周知的著名定理。但黑洞周围的吸积盘中可以存在磁场。本文给出了恒星质量黑洞的吸积盘最内层稳定轨道半径处的磁场强度的实估计。

英文摘要:

X-ray binary systems are very popular objects for astrophysical investigations. Compact objects in these systems are neutron stars, white dwarfs and black holes. Neutron stars and white dwarfs can have intrinsic magnetic fields. There is well known, famous theorem about absence of intrinsic magnetic fields of black holes. But magnetic field can exist in the accretion disk around a black hole. We present here the real estimates of the magnetic field strength at the radius of innermost stable orbit in an accretion disk of stellar mass black holes.
