Neutron And Strange Stars In R-Squared Gravity |
|
Abstract |
We study non-perturbatively and self-consitently neutron and strange stars in $f(R)$ theory of gravity, with $f(R) = R + aR^2$, the so-called $R$-squared gravity. Slowly rotating models as well as f-mode oscillations are thoroughly investigated. The results are compared to the general relativistic ones and the differences in the results are discussed. A high degree of equation of state independence and insensitivity to the gravitational theory of the adopted asteroseismology relations is observed.(ref. S. Yazadjiev, D. Doneva, K. Kokkotas, K.
