QUARK CORE FORMATION IN SPINNING-DOWN PULSARS

摘要

A pulsars spins down due to magnetic torque reducing its radius and increasing the central energy density. Some pulsars which are born with central densities close to the critical value of quark deconfinement may undergo a phase transition and suffer a structural re-arrangement. This process may excite oscillation modes and emit gravitational waves. We determine the rate of quark core formation in neutron stars using a realistic population synthesis code.
