2D Cooling of Magnetized Neutron Stars
Context. Many thermally emitting, isolated neutron stars have magnetic fields that are larger than 1013 G. A realistic cooling model that includes the presence of high magnetic fields should be reconsidered. Aims. We investigate the effects of an anisotropic temperature distribution and Joule heating on the cooling of magnetized neutron stars. Methods. The 2D heat transfer equation with anisotr...
متن کاملNeutrino synchrotron emission from dense magnetized electron gas of neutron stars
We study the synchrotron emission of neutrino pairs by relativistic, degenerate electrons in strong magnetic fields. Particular attention is paid to the case in which the dominant contribution comes from one or several lowest cyclotron harmonics. Calculations are performed using the exact quantum formalism and the quasiclassical approach. Simple analytic fits to the neutrino synchrotron emissiv...
متن کاملThe Impact of Magnetic Field on the Thermal Evolution of Neutron Stars
The impact of strong magnetic fields G on the thermal evolution of neutron stars is investigated, 13 B 1 10 including crustal heating by magnetic field decay. For this purpose, we perform 2D cooling simulations with anisotropic thermal conductivity considering all relevant neutrino emission processes for realistic neutron stars. The standard cooling models of neutron stars are called into quest...
متن کاملHeating and cooling of magnetars with accreted envelopes
We study the thermal structure and evolution of magnetars as cooling neutron stars with a phenomenological heat source in an internal layer. We focus on the effect of magnetized (B 1014 G) non-accreted and accreted outermost envelopes composed of different elements, from iron to hydrogen or helium. We discuss a combined effect of thermal conduction and neutrino emission in the outer neutron sta...
متن کاملThermal Structure and Cooling of Superfluid Neutron Stars with Accreted Magnetized Envelopes
We study the thermal structure of neutron stars with magnetized envelopes composed of accreted material, using updated thermal conductivities of plasmas in quantizing magnetic fields, as well as equation of state and radiative opacities for partially ionized hydrogen in strong magnetic fields. The relation between the internal and local surface temperatures is calculated and fitted by an analyt...
