银河系和河外黑洞周围吸积盘的动力学可能会受到其磁场的影响。本文推广了Abramowicz，Jaroszynski和Sikora的Kerr度规中静止轴对称环面的完全相对论理论，引入了强环向磁场，构造了具有常角动量的正压环面的解析解。这一发展是特别重要的广义相对论计算磁流体力学，遭受缺乏精确的分析解决方案，需要测试计算机代码。
The dynamics of accretion discs around galactic and extragalactic black holes may be influenced by their magnetic field. In this paper, we generalize the fully relativistic theory of stationary axisymmetric tori in Kerr metric of Abramowicz, Jaroszynski & Sikora by including strong toroidal magnetic field and construct analytic solutions for barotropic tori with constant angular momentum. This development is particularly important for the general relativistic computational magnetohydrodynamics that suffers from the lack of exact analytic solutions that are needed to test computer codes.
