Joule heating in high magnetic field pulsars
V. Urpin, D. Konenkov
We study the efficiency of Joule heating in the crustal layers of young neutron stars. It is shown that dissipation of the magnetic field is highly inhomogeneous in the crust with…
Neutrino transport and hydrodynamic stability of rotating proto-neutron stars
V. Urpin
We consider stability of differentially rotating non-magnetic proto-neutron stars. When neutrino transport is efficient, the star can be subject to a diffusive instability that can…
Hydromagnetic Instability in Differentially Rotating Flows
A. Bonanno, V. Urpin
We study the stability of a compressible differentially rotating flows in the presence of the magnetic field, and we show that the compressibility profoundly alters the previous re…
Generation of the magnetic field in jets
V. Urpin
We consider dynamo action under the combined influence of turbulence and large-scale shear in sheared jets. Shear can stretch turbulent magnetic field lines in such a way that even…
Protoneutron star dynamos: pulsars, magnetars, and radio-silent X-ray emitting neutron stars
A. Bonanno, V. Urpin, G. Belvedere
We discuss the mean-field dynamo action in protoneutron stars that are subject to instabilities during the early evolutionary phase. The mean field is generated in the neutron-fing…
Mixing zones in magnetized differentially rotating stars
V. Urpin
We study the secular instability of magnetized differentially rotating radiative zones taking account of viscosity and magnetic and thermal diffusivities. The considered instabilit…
