Static spherically symmetric (SSS) solutions of the quadratic f(R) gravity are studied in the Einstein’s frame under conditions of asymptotic flatness. Following recent dark matter model, we consider the scalaron mass of the order of several meV. We found a representation of the basic equations that...
