Neutron Stars in frames of $R^2$-gravity and Gravitational Waves

Artyom V. Astashenok, Alexey S. Baigashov, Sergey A. Lapin

The realistic models of neutron stars are considered for simple $R+\alpha R^2$ gravity and equivalent Brance-Dicke theory with dilaton field in Einsein frame. For negative values of $\alpha$…
