40. Neutron stars as cosmic laboratories for superfluid dynamics

Talk

Owing to the extreme densities, pressures and low (on the nuclear physics scale) temperatures of their interiors, neutron stars act as cosmic laboratories for superfluid dynamics. The theoretical motivation for this is well established and pulsar glitches – sudden spin-up events followed by a gradual relaxation – provide convincing observational support. Nevertheless, and despite about half a...

Low-field magnetars have dipolar magnetic fields of $10^{12}$--$10^{13}$ G, 10-100 times weaker than the values of magnetic-field strength $B\approx$ $10^{14}$--$10^{15}$ G used to define classical magnetars, yet they produce similar X-ray bursts and outbursts. Using direct numerical simulations of magnetothermal evolution starting from a dynamo-generated magnetic field, we show that the...
