Neutrino Emissivity of Dense Stars
The neutrino emissivity of compact stars is investigated in this work. We consider stars consisting of nuclear as well as quark matter for this purpose. Different models are used to calculate the composition of nuclear and quark matter and the neutrino emissivity. Depending on the model under consideration, the neutrino emissivity of nuclear as well as quark matter varies over a wide range. We ...
متن کاملBaryon superfluidity and neutrino emissivity of neutron stars
For neutron stars with hyperon-mixed core, neutrino emissivity is studied under the equation of state, obtained by introducing three-body force universal for all baryons so as to assure the maximum mass compatible with the observation. By paying attention to the density dependence of the critical temperatures of the baryon superfluids, which reflect the nature of baryon-baryon interaction and c...
متن کاملTransport Properties and Neutrino Emissivity of Dense Neutron–star Matter with Localized Protons
(Received February 1, 2008) As pointed out by Kutschera and Wójcik, very low concentration of protons combined with a specific density dependence of effective neutron– proton interaction could lead to a localization of “proton impurities” in neutron medium at densities exceeding four times normal nuclear matter density. We study consequences of the localization of protons for transport processe...
متن کاملNeutrino emissivity and bulk viscosity of iso-CSL quark matter in neutron stars
We present results for neutrino emissivities and bulk viscosities of a two-flavor color superconducting quark matter phase with isotropic color-spin-locked (iso-CSL) single-flavor pairing which fulfill the constraints on quark matter derived from cooling and rotational evolution of compact stars. We compare with results for the phenomenologically successful, but yet heuristic 2SC+X phase.
متن کاملNeutrino Emissivity of Degenerate Quark Matter
An exact numerical calculation of neutrino emissivity of two and three flavour quark matter have been carried out. We find that the neutrino emissivity obtained from the Iwamoto formula is in qualitative agreement with our calculation for two flavour quark matter. For three flavour case, on the other hand we find that the Iwamoto formula overestimates the numerical values by ∼2 orders of magnit...
