Schwarzschild黑洞在类Chaubergin气体宇宙中的演化

Evolution of a Schwarzschild Black Hole in Phantom-like Chaplygin gas Cosmologies

Mubasher Jamil

摘要:

在经典的相对论范围内,虚能量在黑洞上的吸积减少了黑洞的质量。在这种背景下,我们研究了宇宙学标准模型中的Schwarzschild黑洞的演化,使用类幻影的修改变量Chaubergin气体和粘性广义Chaubergin气体。导出了相应的吸积时标和质量演化表达式。我们的结果表明,如果吸积的幻影Chaubergin气体违反优势能量条件,则黑洞的质量将减小,反之则将增加。因此,我们的结果与Babichev \textit{et al} \cite{Babi1}的结果是一致的,谁首先提出了这种情况。

英文摘要:

In the classical relativistic regime, the accretion of phantom energy onto a black hole reduces the mass of the black hole. In this context, we have investigated the evolution of a Schwarzschild black hole in the standard model of cosmology using the phantom-like modified variable Chaplygin gas and the viscous generalized Chaplygin gas. The corresponding expressions for accretion time scale and evolution of mass have been derived. Our results indicate that mass of the black hole will decrease if the accreting phantom Chaplygin gas violates the dominant energy condition and will increase in the opposite case. Thus our results are in agreement with the results of Babichev \textit{et al} \cite{Babi1} who first proposed this scenario.
