46. Bulk viscosity and damping of density oscillations in binary neutron star mergers

Dr Arus Harutyunyan (Byurakan Astrophysical Observatory, Yerevan State University)

Talk

Bulk viscosity in neutron stars plays an important role in the dynamics of binary neutron star mergers by damping density oscillations in the post-merger remnant. In this talk, I will review the computation of bulk viscosity in the warm, dense, neutrino-transparent cores of neutron stars for two possible compositions: nuclear matter and quark matter. For the nuclear matter equation of state...

37. Beyond the Taylor Expansion: Systematics in the phase of continuous gravitational wave

Talk

Studying isolated asymmetric neutron stars via continuous gravitational waves has become a new approach to understanding neutron star physics, given improvements in detector sensitivity and the upcoming next-generation detectors like the Einstein Telescope, which will make detection of these signals feasible in the near future. In our work, we investigate whether corrections to the...

53. Self-consistently connecting the neutron star mode spectrum to fundamental nuclear physics

Duncan Neill (University of Bath)

Talk

Neutron star (NS) asteroseismology is a powerful tool for probing the nature of matter inside NSs, with various oscillation modes being sensitive to different properties of matter in different regions of the star, and thus to different aspects of fundamental nuclear physics. Current asteroseismic studies however focus on particular families of oscillation modes, or rely on phenomenological...
