AI总结:

本文证明了广义相对论中极限紧致性对象——黑洞和布赫达尔星的稳定性,无论扰动性质如何,其平衡状态均保持稳定。

摘要:

在广义相对论中,存在两种极限紧致性对象,一种具有一个定义黑洞视界的null边界,另一种具有一个timelike边界定义布赫达尔星。这两种对象由引力能量等于或等于一半的质量来特征化。由于非引力质量-能量是引力能量的来源,这两种对象显然都是稳定的。在本文中,我们以简单而一般的方式证明,定义对象的平衡状态确实稳定,无论扰动的性质如何。

英文摘要:

In General Relativity, there exist two objects of limiting compactness, one with a null boundary defining the horizon of a black hole and the other with a timelike boundary defining a Buchdahl star. The two are characterized by gravitational energy equal to or half the mass. Since non-gravitational mass-energy is the source of gravitational energy, both of these objects are manifestly stable. We demonstrate in this letter, in a simple and general way, that the equilibrium state defining the object is indeed stable, independent of the nature of the perturbation.
