最小几何变形方法的推广

The Minimal Geometric Deformation Approach Extended

Roberto Casadio, Jorge Ovalle, Roldao da Rocha

摘要:

最小几何变形方法是为了在Randall-Sundrum膜世界框架下研究球对称自引力系统(如恒星或类似天体)周围的外部时空而引入的。一个一致的扩展,这种方法在这里开发,它包含修改的时间分量和径向分量的球对称度量。一个修改的史瓦西几何作为其最简单的应用程序的一个例子,和一个新的解决方案可能有用的描述恒星在膜世界。

英文摘要:

The minimal geometric deformation approach was introduced in order to study the exterior space-time around spherically symmetric self-gravitating systems, like stars or similar astrophysical objects as well, in the Randall-Sundrum brane-world framework. A consistent extension of this approach is developed here, which contains modifications of both the time component and the radial component of a spherically symmetric metric. A modified Schwarzschild geometry is obtained as an example of its simplest application, and a new solution potentially useful to describe stars in the brane-world is also presented.
