Gravitational Waves from Spinning Neutron Stars
This paper gives an introductory overview of the search for continuous gravitational waves from spinning neutron stars. We review the current theoretical understanding of possible emission mechanisms and the expected strength of signals received on Earth. Given the substantial uncertainties involved in neutron star physics, these searches — if sufficiently sensitive — can provide important new ...
متن کاملPhase Diagram for Spinning and Accreting Neutron Stars
Neutron star configurations are considered as thermodynamical systems for which a phase diagram in the angular velocity (Ω) baryon number (N) plane is obtained with a dividing line Ncrit(Ω) for quark core configurations. Trajectories of neutron star evolution in this diagram are studied for different scenarios defined by the external torque acting on the star due to radiation and/or mass accret...

متن کاملData analysis of gravitational-wave signals from spinning neutron stars. I. The signal and its detection
We present a theoretical background for the data analysis of the gravitational-wave signals from spinning neutron stars for Earth-based laser interferometric detectors. We introduce a detailed model of the signal including both the frequency and the amplitude modulations. We include the effects of the intrinsic frequency changes and the modulation of the frequency at the detector due to the Ear...
متن کاملParameter choices and ranges for continuous gravitational wave searches for steadily spinning neutron stars
We consider the issue of selecting parameters and their associated ranges for carrying out searches for continuous gravitational waves from steadily rotating neutron stars. We consider three different cases: (i) the ‘classic’ case of a star spinning about a principal axis; (ii) a biaxial star, not spinning about a principal axis; (iii) a triaxial star spinning steady, but not about a principal ...
