Description
At high pressure, nuclear matter will undergo a transition to
quark matter, so sufficiently heavy neutron stars may really be
``hybrid stars'' with quark matter cores. We discuss possible
signatures of the presence of a quark matter core, such as
characteristics of the mass-radius relation, and the allowed
range of values of the spin frequency, which is sensitive to
quark matter in the core via the
r-mode spindown mechanism. We also present a new form of dissipation of
r-modes that is expected to occur in hybrid stars:
"phase conversion dissipation".
