摘要
本文首先从一般的角度讨论了球对称均匀星的引力坍缩问题,并且将该问题总结为求解两个一阶非线性的微分方程组;然后具体计算了当星体的状态方程为p=βζ(此处β是一个常数)时的坍缩解;最后我们对该问题作了进一步的讨论并指出外部观察者是无法观察星体坍缩到Schwarzschild半径之后的情况。
In this paper we study the gravilational collapse of spherically symmetricl homogeneous stars. We obtain exact solutions in the given equation of state p=βρ(here β=const), and the exact collapse solutions are also discussed, it is shown that after stars becoming Schwarzschild black holes an outside observer can not abtain any information about the stars.
