Anisotropic compact stars in f(R) gravity

GGL Nashed, S Capozziello - The European Physical Journal C, 2021 - Springer
We derive a new interior solution for stellar compact objects in f (R) gravity assuming a
differential relation to constrain the Ricci curvature scalar. To this aim, we consider specific …
