abstract = "We briefly review the properties of quasi-normal modes of neutron
stars and black holes. We analyse the consequences of a possible
detection of such modes via the gravitational waves associated
with them, especially addressing our study to the Brazilian
spherical antenna, on which a possible detection would occur at
3.0 - 3.4 kHz. A question related to any putative gravitational
wave detection concerns the source that produces it. We argue
that, since the characteristic damping times for the gravitational
waves of neutron stars and black holes are different, a detection
can distinguish between them, and also distinguish the neutron
star's oscillating modes. Moreover, since the source can be
identified by its characteristic damping time, we are able to
extract information about the neutron star or black hole. This
information would lead, for example, to a strong constraint in the
nuclear matter equation of state, namely the compression modulus
should be K approximate to 220 MeV.",
