Relativistic stars in Starobinsky gravity with the matched asymptotic expansions method

Savaş Arapoğlu, Sercan Çıkıntoğlu, K. Yavuz Ekşi

We study the structure of relativistic stars in $\mathcal{R}+\alpha {\mathcal{R}}^2$ theory using the method of matched asymptotic expansion to handle the higher order derivatives in fie…
