Reissner-Nordström-(anti-)de Sitter时空中的Bondi型吸积

Bondi-type accretion in the Reissner-Nordström-(anti-)de Sitter spacetime

Filip Ficek

摘要:

在本文中,我研究的静态,球对称吸积流体到一个带电黑洞的存在下的宇宙学常数。对于某些等温状态方程,有可能得到解析解。在辐射流体的情况下,我指出了层位和声波(临界)点之间的联系。在特定情况下,解在速度与半径的相图中形成封闭的、类似双目的轨迹。

英文摘要:

In this paper I study stationary, spherically symmetric accretion of fluids onto a charged black hole in the presence of the cosmological constant. For some isothermal equations of state it is possible to obtain analytic solutions. In the case of a radiation fluid I point out a connection between locations of the horizons and the sonic (critical) points. In specific cases the solutions form closed, binoculars-like trajectories in a phase diagram of the velocity vs. radius.
