Probing general relativity with neutron star oscillations

Abstract: With the dawn of the era of gravitational wave astronomy, a new window has opened to probe general relativity in the regime of strong gravitational fields. For this purpose, it is important to understand how predictions of modified theories of gravity compare to those of general relativity in this regime, and whether they can be discerned by observations. In this talk I will discuss some implications of modified theories of gravity for equilibrium and perturbative properties of neutron stars, focusing on their oscillation spectrum.
