Homogeneous spherically symmetric bodies with a nonminimal coupling between curvature and matter: the choice of the Lagrangian density for matter
arXiv:1306.1177
Abstract
In this work we study how a nonminimal coupling between matter and gravity can modify the structure of a homogeneous spherical body. The physical relevance of the adopted Lagrangian density is ascertained, with results obtained for two different choices of the latter.
