关于相对论声学几何在黑洞轴对称物质流广义扰动方案下的可实现性

On the realizability of relativistic acoustic geometry under a generalized perturbation scheme for axisymmetric matter flow onto black holes

Deepika B. Ananda, Sourav Bhattacharya, Tapas K. Das

摘要:

我们提出了一种新的线性微扰方法来研究天体物理黑洞周围轴对称物质流的定常跨音速积分解的稳定性。我们讨论的相对论声学几何的出现作为这样的稳定性分析的结果。因此,我们的工作在两个明显不重叠的研究领域--吸积天体物理学和类似的引力现象--之间建立了重要的联系。

英文摘要:

We propose a novel linear perturbation scheme to study the stability properties of the stationary transonic integral solutions for axisymmetric matter flow around astrophysical black holes for the Schwarzschild as well as for rotating Rindler space time. We discuss the emergence of the relativistic acoustic geometry as a consequence of such stability analysis. Our work thus makes a crucial connection between two apparently non-overlapping fields of research - the accretion astrophysics and the analogue gravity phenomena.
