Gravitational Waves from Phase Transition of Accreting Neutron Stars
We propose that when neutron stars in low-mass X-ray binaries accrete
sufficient mass and become millisecond pulsars, the interiors of these stars
may undergo phase transitions, which excite stellar radial oscillations. We
show that the radial oscillations will be mainly damped by gravitational-wave
radiation instead of internal viscosity. The gravitational waves can be
detected by the advanced Laser Interferometer Gravitational-Wave Observatory at
a rate of about three events per year.Comment: Latex, article style, approximately 10 page
