Equation of State of Neutron Stars with Junction Conditions in the Starobinsky Model

Wei-Xiang Feng, Chao-Qiang Geng, W. F. Kao +1

We study the Starobinsky or $R^2$ model of $f(R)=R+\alpha R^2$ for neutron stars with the structure equations represented by the coupled differential equations and the \emph{polytropic}…
