Juan Carlos Degollado, Dario Nunez, Carlos Palenzuela

摘要:

在一般D型时空中,导出了包含物质源项的$Ψ_4$ Weyl标量微扰方程的显式形式.它是详细描述的特殊情况下,史瓦西时空使用进入穿透坐标。作为一个实际应用,我们重点研究了当黑洞受到周围尘埃状流体物质扰动时引力波的发射。时空的对称性和物质源的简单性允许通过球谐分解来研究一维数值代码的问题。

英文摘要:

The explicit form of perturbation equation for the $Ψ_4$ Weyl scalar, containing the matter source terms, is derived for general type D spacetimes. It is described in detail the particular case of the Schwarzschild spacetime using in-going penetrating coordinates. As a practical application, we focused on the emission of gravitational waves when a black hole is perturbed by a surrounding dust-like fluid matter. The symmetries of the spacetime and the simplicity of the matter source allow, by means of a spherical harmonic decomposition, to study the problem by means of a one dimensional numerical code.
