Abstract

Static spherically symmetric (SSS) solutions of f(R) gravity are studied in the Einstein frame. The solutions involve SSS configuration mass M and scalaron mass μ\mu (in geometrized units); for typical astrophysical masses, the dimensionless parameter MμM\mu has very large value. We found analytic solutions on a finite interval for MμM\mu\to \infty in case of a family of scalaron potentials. The asymptotically flat solutions on (0,)(0,\infty) have been studied numerically for MμM\mu up to 102010^{20} in case of the quadratic f(R) model.
