Polytropic spheres in Palatini f(R) gravity
arXiv:0801.4852 · doi:10.1051/eas:0830023
Abstract
We examine static spherically symmetric polytropic spheres in Palatini f(R) gravity and show that no regular solutions to the field equations exist for physically relevant cases such as a monatomic isentropic gas or a degenerate electron gas, thus casting doubt on the validity of Palatini f(R) gravity as an alternative to General Relativity.
