Inferring neutron-star properties from gravitational-wave signals of binary mergers

Understand

The oscillations of a merger remnant forming after the coalescence of two neutron stars are very characteristic for the high-density equation of state.

• The dominant oscillation frequency occurs as a pronounced peak in the kHz range of the gravitational-wave spectrum.
• We describe how the dominant oscillation frequency of the remnant can be employed to infer the radii of non-rotating neutron stars.
