论文摘要
最近的各种理论研究表明，如果国家方程式通过普遍的不确定性原理（GUP）描述，则保留白矮人的重力崩溃。已经有一些尝试恢复Chandrasekhar限制的尝试，但是从不同的角度来看，它们是不足的，其中一些导致了非物理的群众关系。在本文中，我们通过分析一般相对论中的动态不稳定性来严格解决此问题。我们证实了Chandrasekhar极限的存在以及稳定的质量 - 拉迪乌斯曲线，这些曲线与天文观测保持一致。此外，这种稳定性分析表明，与白矮人相比，重力崩溃超出了Chandrasekhar极限，这表明紧凑物体的可能性更密集。
Various recent theoretical investigations suggest that gravitational collapse of white dwarfs is withheld for arbitrarily high masses if the equation of state is described by the generalized uncertainty principle (GUP). There have been a few attempts to restore the Chandrasekhar limit but they are found to be inadequate from different perspectives and some of them led to unphysical mass-radius relations. In this paper, we rigorously resolve this problem by analyzing the dynamical instability in general relativity. We confirm the existence of Chandrasekhar's limit as well as stable mass-radius curves that behave consistently with astronomical observations. Moreover, this stability analysis suggests gravitational collapse beyond the Chandrasekhar limit signifying the possibility of compact objects denser than white dwarfs.
