带电球对称物体中的束缚

Binding in charged spherically symmetric objects

Matthew Corne, Arkady Kheyfets, Jennifer Piasio, Chad Voegele

摘要:

我们考虑的主题,自约束的静态,球对称的物体组成的带电流体。我们以前已经表明,在一个完美的流体的情况下,只有局部部分的质量有助于引力的自我约束的对象,并在限制的情况下,纯粹由电磁质量的对象,没有引力约束。在这里,我们将这个结果推广到更一般的各向异性流体的情况。我们的检查奥本海默-Volkov方程允许跟踪引力和非引力的贡献绑定的球对称物体,并表明,那些纯电磁质量不存在。

英文摘要:

We consider the subject of self--binding in static, spherically symmetric objects consisting of a charged fluid. We have shown previously that in the case of a perfect fluid, only the localized part of the mass contributes to gravitational self--binding of such objects and that in the limiting case of objects comprised purely of electromagnetic mass, there is no gravitational binding. Here, we extend this result to the more general case of an anisotropic fluid. Our inspection of the Oppenheimer--Volkov equation allows tracking of both gravitational and non-gravitational contributions to binding of spherically symmetric objects and shows that those with pure electromagnetic mass cannot exist.
