相对论性自引力流体中的空穴演化

Cavity evolution in relativistic self-gravitating fluids

L. Herrera, G. Le Denmat, N. O. Santos

摘要:

我们考虑球对称相对论流体内空腔的演化,假设相邻流体元素之间的适当径向距离在其演化过程中保持不变(纯区域演化条件)。一般形式主义部署和解决方案。其中一些满足Darmois条件,而另一些则在一个或两个边界表面上呈现壳,并且必须满足以色列条件。这些结果的一些天体物理方案的前瞻性应用建议。

英文摘要:

We consider the evolution of cavities within spherically symmetric relativistic fluids, under the assumption that proper radial distance between neighboring fluid elements remains constant during their evolution (purely areal evolution condition). The general formalism is deployed and solutions are presented. Some of them satisfy Darmois conditions whereas others present shells and must satisfy Israel conditions, on either one or both boundary surfaces. Prospective applications of these results to some astrophysical scenarios is suggested.
