摘要

应用（1+1+2）协变形式给出了f(R)重力下非真空静态球对称时空的协变描述。然后利用传播方程推导出托尔曼-奥本海默-沃尔科夫方程的协变无量纲形式。然后，我们给出了这些方程的解策略，并得到了一些新的精确解，这些解对标准物质具有正确的热力学性质。

Some exact relativistic star solutions in f(R) gravity

We present a covariant description of non-vacuum static spherically symmetric spacetimes in f(R) gravity applying the (1+1+2) covariant formalism. The propagation equations are then used to derive a covariant and dimensionless form of the Tolman–Oppenheimer–Volkoff equations. We then give a solution strategy to these equations and obtain some new exact solutions for the particular case , which have the correct thermodynamic properties for standard matter.
