尘埃球的引力坍缩

The gravitational collapse of a dust ball

Trevor W. Marshall

摘要:

结果表明,经典的Oppenheimer和Snyder模型对坍缩的描述不能满足球表面的一个重要匹配条件。在修正模型,使内部和外部的度量正确匹配后,它建立了收缩过程停止在史瓦西半径,在球的表面有一个粒子的积累,并在无限的时间推移的限制,在表面的粒子密度变得无限。黑洞不可能形成。这一结果证实了爱因斯坦和爱丁顿关于当坍缩速度接近光速时发生引力坍缩的判断。

英文摘要:

It is shown that the description of collapse given by the classic model of Oppenheimer and Snyder fails to satisfy a crucial matching condition at the surface of the ball. After correcting the model so that the interior and exterior metrics match correctly, it is established that the contraction process stops at the Schwarzschild radius, that there is an accumulation of particles at the surface of the ball, and that in the limit of infinite time lapse the density of particles at the surface becomes infinite. A black hole cannot form. This result confirms the judgements of both Einstein and Eddington about gravitational collapse when the collapse velocity approaches that of light.
