Orbital stability, relativistic precession, and QPO constraints for constant-curvature black holes in $f(R)$ gravity

Kourosh Nozari, Sara Saghafi, Khadijeh Salahshour +1

We analyze circular-orbit stability, epicyclic resonances, relativistic precession, and quasi-periodic-oscillation (QPO) constraints in the constant-curvature vacuum sector of metr…
