Modifications to the pulsar kick velocity due to magnetic interactions in dense plasma

In this work we calculate the pulsar kick velocity of a magnetized neutron star (NS) composed of a degenerate quark matter core with non-Fermi liquid (NFL) correction. Both the leading order (LO) and next to LO (NLO) corrections to the kick velocity have been incorporated. In addition, the NFL corrections to the specific heat of magnetized quark matter have been presented. This has been taken into account to calculate the kick velocity of the NS. The results show a significant departure from the normal Fermi liquid estimates. The relation between radius and temperature has been shown with a kick velocity of 100 km s−1 with and without NFL corrections.

Next to leading order non Fermi liquid corrections to the neutrino emissivity and cooling of the neutron star

In this work we derive the expressions of the neutrino mean free path(MFP) and emissivity with non Fermi liquid corrections up to next to leading order(NLO) in degenerate quark matter. The calculation has been performed both for the absorption and scattering processes. Subsequently the role of these NLO corrections on the cooling of the neutron star has been demonstrated. The cooling curve shows moderate enhancement compared to the leading order(LO) non-Fermi liquid result. Although the overall correction to the MFP and emissivity are larger compared to the free Fermi gas, the cooling behavior does not alter significantly.
