球壳的牛顿和广义相对论模型

Newtonian and General Relativistic Models of Spherical Shells

D. Vogt, P. S. Letelier

摘要:

利用简单的牛顿势-密度对导出了一族变厚度球壳。然后,一个特殊的各向同性形式的度规在球坐标系中被用来构建一个广义相对论版本的牛顿家庭的壳。这些相对论性壳层的物质呈现相等的方位和极压,而径向压力是切向压力的常数倍。我们还首次研究了牛顿壳族和相对论壳族的稳定性。

英文摘要:

A family of spherical shells with varying thickness is derived by using a simple Newtonian potential-density pair. Then, a particular isotropic form of a metric in spherical coordinates is used to construct a General Relativistic version of the Newtonian family of shells. The matter of these relativistic shells presents equal azimuthal and polar pressures, while the radial pressure is a constant times the tangential pressure. We also make a first study of stability of both the Newtonian and relativistic families of shells.
