Probing the interior of neutron stars with gravitational waves

Abstract

We show here how the internal structure of a neutron star can be inferred from its gravitational wave spectrum. Under the premise that the frequencies and damping rates of a few $w$-mode oscillations are found, we apply an inversion scheme to determine its mass, radius and density distribution. In addition, accurate equation of state of nuclear matter can also be determined.
