Neutron star spin-kick velocity correlation effect on binary neutron star coalescence rates and spin-orbit misalignment of the components
We study the effect of the neutron star spin – kick velocity alignment observed in young radio pulsars on the coalescence rate of binary neutron stars. Two scenarios of the neutron star formation are considered: when the kick is always present and when it is small or absent if a neutron star is formed in a binary system due to electroncapture degenerate core collapse. The effect is shown to be ...
متن کاملSpin-Kick Correlation in Neutron Stars: Alignment Conditions and Implications
Recent observations of pulsar wind nebulae and radio polarization profiles revealed a tendency of the alignment between the spin and velocity directions in neutron stars. We study the condition for spin-kick alignment using a toy model, in which the kick consists of many off-centered, randomly-oriented thrusts. Both analytical considerations and numerical simulations indicate that spin-kick ali...
متن کامل1 Spin susceptibility of neutron matter at zero temperature
The Auxiliary Field Diffusion Monte Carlo method is applied to compute the spin susceptibility and the compressibility of neutron matter at zero temperature. Results are given for realistic interactions which include both a two–body potential of the Argonne type and the Urbana IX three–body potential. Simulations have been carried out for about 60 neutrons. We find an overall reduction of the s...

متن کاملSpin-asymmetry energy of nuclear matter
We calculate the density-dependent spin-asymmetry energy S(kf ) of isospin-symmetric nuclear matter in the three-loop approximation of chiral perturbation theory. The interaction contributions to S(kf ) originate from one-pion exchange, iterated one-pion exchange, and (irreducible) two-pion exchange with no, single, and double virtual ∆-isobar excitation. We find that the truncation to 1π-excha...
