论文摘要
在一般积聚磁盘模型理论中，围绕天文对象的积聚盘包括遵守开普勒运动的流体环。但是，当我们靠近旋转的紧凑型物体（例如黑洞或中子星）的积聚磁盘中心时，我们应该考虑相对论和旋转效应。在这项研究中，我们探讨了在Mukhopadhyay的伪牛顿电位近似的背景下，对于完整的一般相对论理论，积聚磁盘内部的几何形状。我们发现积聚磁盘的形状“膨化”或变厚，并且磁盘的光度可能超过紧凑型黑洞表面附近的Eddington发光度。
In the general accretion disk model theory, the accretion disk surrounding an astronomical object comprises fluid rings obeying Keplerian motion. However, we should consider relativistic and rotational effects as we close in toward the center of accretion disk surrounding spinning compact massive objects such as a black hole or a neutron star. In this study, we explore the geometry of the inner portion of the accretion disk in the context of Mukhopadhyay's pseudo Newtonian potential approximation for the full general relativity theory. We found that the shape of the accretion disk "puffs up" or becomes thicker and the luminosity of the disk could exceed the Eddington luminosity near the surface of the compact spinning black hole.
