Gravitational Waves from Phase Transitions of Accreting Neutron Stars
نویسنده
چکیده
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.

Detecting gravitational waves from accreting neutron stars
The gravitational waves emitted by neutron stars carry unique information about their structure and composition. Direct detection of these gravitational waves, however, is a formidable technical challenge. In a recent study we quantified the hurdles facing searches for gravitational waves from the known accreting neutron stars, given the level of uncertainty that exists regarding spin and orbit...
متن کاملGravitational waves from neutron stars: recent developments
The gravitational waves that bathe the Earth presumably do not vary wildly in strength from year to year. However, our very imperfect understanding of their strengths occasionally does change abruptly, prompted either by new astrophysical observations or by new theoretical predictions and discoveries. Such has been the case in the last year for our expectations for periodic gravitational waves ...
متن کاملGravitational Waves from Neutron Stars: A Review
Neutron stars are excellent emitters of gravitational waves. Squeezing matter beyond nuclear densities invites exotic physical processes, many of which violently transfer large amounts of mass at relativistic velocities, disrupting spacetime and generating copious quantities of gravitational radiation. I review mechanisms for generating gravitational waves with neutron stars. This includes grav...
متن کاملR-modes in Accreting and Young Neutron Stars
Recent work has raised the exciting possibility that r-mode pulsations (Rossby waves) in rotating neutron star cores may be strong gravitational wave sources. Rapidly rotating young neutron stars born in supernovae enter the r-mode instability region within the first minutes of their lives and may spin down by substantial amounts due to gravitational radiation from r-modes. Accreting neutron st...
متن کاملGravitational Waves and the Maximum Spin Rate of Accreting Neutron Stars
Accreting neutron stars in the weakly magnetic Low-Mass XRay Binaries (LMXBs) are expected to be spun up near the breakup frequency ∼> 1 kHz in a small fraction of their age. The lack of observed systems above ∼ 600−700Hz has led to the suggestion that gravitational-wave spindown torque may be setting a maximum rotation rate. If true, searches for sub-millisecond radio pulsars will not be succe...
