Cosmological Gravitational Wave Background from Phase Transitions in Neutron Stars
It has recently been suggested that collapse of neutron stars induced by a phase transition to quark matter can be a considerable source of gravitational waves with kHz frequencies. We demonstrate that if about one percent of all neutron stars undergo this process, the resulting cosmological gravitational wave background would reach about 10 times the critical density. The background would peak...
متن کاملPhase Transitions in Neutron Stars and Maximum Masses.
Using the most recent realistic effective interactions for nuclear matter with a smooth extrapolation to high densities including causality, we constrain the equation of state and calculate maximum masses of rotating neutron stars. First- and second-order phase transitions to, e.g., quark matter at high densities are included. If neutron star masses of approximately 2.3 M middle dot in circle f...
متن کاملQuark-Hadron Phase Transitions in Young and Old Neutron Stars
The mixed phase of quarks and hadrons which might exist in the dense matter encountered in the varying conditions of temperature and trapped neutrino fraction in proto-neutron stars is studied. The extent that the mixed phase depends upon the thermodynamical parameters as well as on the stiffness of matter in the hadronic and quark phases is discussed. We show that hadronic equations of state t...
متن کاملGravitational Waves from Phase Transitions 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...
متن کاملPossible Signatures of Quark-hadron Phase Transitions inside Neutron Stars
The sky has long been a successful test ground and discovery site for fundamental physics. Examples include the discovery of Helium from the solar spectrum in 1868, evidence for gravity waves from binary pulsars 1 in 1978, and more recently in 1985, the discovery of Bucky Balls (C60), though not directly in the sky, through experiments designed to simulate environments near stars in favor of fo...
