Neutron star equation of state from gravitational waves detections |
Abstract _ |
We briefly review the properties of quasi-normal modes of neutron stars and black holes. Specially addressing our study to the Brazilian spherical antenna, on which a possible detection would occur at 3.0-3.4 kHz, we analyze the consequences of a possible detection of such quasi-normal modes. Since the source can be identified, by its characteristic damping time, we are able to extract information about the neutron star or black hole. These information lead to a strong constrain in the nuclear matter equation of state, namely, the compression modulus should be K = 220 MeV. |
