FAST COOLING OF NEUTRON STARS: SUPERFLUIDITY vs. HEATING AND ACCRETED ENVELOPE
It is generally considered that the neutron star cooling scenarios involving fast neutrino emission, from a kaon or pion condensate, quark matter, or the direct Urca process, require the presence of baryon pairing in the central core of the star to control the strong neutrino emission and produce surface temperatures compatible with observations. I show here that within the kaon condensate scen...
متن کاملCooling of neutron stars: effects of accreted envelopes, magnetic field and crustal superfluidity
We briefly review recent theoretical studies of the effects of accreted envelopes, magnetic fields and crustal superfluidity on the cooling of neutron stars. These effects are especially important for slowly cooling low-mass neutron stars, where direct Urca process of neutrino emission is forbidden. The effects are useful for interpretation of observations of several isolated middle-aged neutro...
متن کاملCooling Neutron Stars with Accreted Envelopes
Gilles Chabrier1, Alexander Y. Potekhin2;1;3, and Dmitry G. Yakovlev2 ABSTRACT The relationships between the e ective surface temperature Te and internal temperature Tb of nonmagnetized neutron stars with and without accreted envelopes are calculated for Te > 5 104 K. We use updated equations of state and radiative opacities, and we improve considerably the electron conductive opacity. We exami...
متن کاملInternal temperatures and cooling of neutron stars with accreted envelopes
The relationships between the effective surface (Teff ) and internal temperatures of neutron stars (NSs) with and without accreted envelopes are calculated for Teff > 5 × 104 K using new data on the equation of state and opacities in the outer NS layers. We examine various models of accreted layers (H, He, C, O shells produced by nuclear transformations in accreted matter). We employ new Opacit...
متن کاملMinimal models of cooling neutron stars with accreted envelopes
We study the ‘minimal’ cooling scenario of superfluid neutron stars with nucleon cores, where the direct Urca process is forbidden and enhanced cooling is produced by neutrino emission due to the Cooper pairing of neutrons. Extending our recent previous work, we include the effects of surface accreted envelopes of light elements. We employ the phenomenological density-dependent critical tempera...
