Gravitational wave asteroseismology of neutron and strange stars in $R^2$ gravity

Understand

We study the oscillations of neutron and strange stars in $R^2$ gravity.

• More precisely the nonradial $f$-modes are examined and the differences with pure general relativity are investigated.
• Using these results we build several gravitational wave asteroseismology relations.
• Our goal is to determine up to what extend these relations are equation of state independent and whether they deviate enough from general relativity in order to produce an observable effect.
