contents 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 $μ$ (in geometrized units); for typical astrophysical masses, the dimensionless parameter $Mμ$ has very large value. We found analytic solutions on a finite interval for $Mμ\to \infty$ in case of a family of scalaron potentials. The asymptotically flat solutions on $(0,\infty)$ have been studied numerically for $Mμ$ up to $10^{20}$ in case of the quadratic f(R) model.
