In our work, we use bayesian inference to study how the inclusion of a scalar-isovector interaction channel within a RMF framework can affect the threshold for the direct URCA process in the core of neutron stars. We also study the effect of proton pairing by including a simplified model for the proton 1S0 pairing gap. The results show that the inclusion of the new interaction channel can...

We perform a statistical analysis of the thermal evolution of isolated neutron stars (NSs) by confronting theoretical cooling curves with luminosity–age measurements for 24 sources. For each object, we explore five purely nucleonic equations of state—APR4, FSU2R, DD2, IST, and NL3$\omega\rho$—combined with representative models of neutron superfluidity and proton superconductivity, while...

45. Persistent gravitational radiation from glitching pulsars

Talk

Neutron star glitches may be caused by the sudden unpinning and collective movement of vortices in the superfluid condensate inside the star, also known as vortex avalanches. The metastable vortex configuration between avalanches is determined by the far-from-equilibrium avalanche dynamics and is nonaxisymmetric in general, producing a small but nonzero current quadrupole moment which...
