磁场在非均匀引力坍缩中的作用

Role of a magnetic field in the context of inhomogeneous gravitational collapse

Shibendu Gupta Choudhury

摘要:

已经发现磁场具有抵抗重力的固有能力。文献中提出的一个重要问题是磁场的存在是否会改变引力坍缩的动力学,并阻止奇点的最终形成。在这种情况下,不均匀的崩溃模型还没有得到显着的探讨。本文研究了磁场在非均匀柱对称模型演化中的作用。我们使用基于Raychaudhuri方程的方法进行这样的分析。我们证明了在这些模型中磁场完全有可能避免引力坍缩。

英文摘要:

Magnetic fields have been found to have an inherent capability of acting against gravity. An important question posed in the literature is whether presence of a magnetic field can alter the dynamics of a gravitational collapse and prevent the final formation of a singularity. Inhomogeneous models of collapse have not been explored significantly in this context. In the present work we investigate the role of magnetic fields in the evolution of inhomogeneous cylindrically symmetric models. We use an approach based on the Raychaudhuri equation for such an analysis. We show that it is quite possible for the magnetic field to avert the gravitational collapse in these models.
