Neutrino-pair emission due to electron-phonon scattering in a neutron star crust
Neutrino-pair bremsstrahlung radiation is considered due to electron–phonon scattering of degenerate, relativistic electrons in a lattice of spherical atomic nuclei in a neutron star crust. The neutrino energy generation rate is calculated taking into account exact spectrum of phonons, the Debye–Waller factor, and the nuclear form–factor in the density range from 10 g cm to 10 g cm at arbitrary...
متن کاملNeutrino pair bremsstrahlung in neutron star crusts: A reappraisal.
We demonstrate that band-structure effects suppress bremsstrahlung of neutrino pairs by electrons in the crusts of neutron stars at temperatures of the order of 5×109K and below. Taking this into account, together with the fact that recent work indicates that the masses of neutron star crusts are considerably smaller than previously estimated, we find neutrino pair bremsstrahlung to be much les...
متن کاملNeutrino-pair bremsstrahlung by electrons in neutron star crusts
Neutrino-pair bremsstrahlung by relativistic degenerate electrons in a neutron-star crust at densities 109 g cm −3 <∼ ρ <∼ 1.5 × 1014 g cm−3 is analyzed. The processes taken into account are neutrino emission due to Coulomb scattering of electrons by atomic nuclei in a Coulomb liquid, and electronphonon scattering (the phonon contribution) and Bragg diffraction (the static-lattice contribution)...
متن کاملEffects of Electron Band Structure on Neutrino Pair Bremsstrahlung in Neutron Star Crusts
We calculate the rate of energy emission by bremsstrahlung of neutrino pairs by electrons moving in the crystalline lattice of ions in dense matter in the crust of a neutron star. Since the periodic potential in the solid gives rise to electronic band gaps which can be as large as about 1 MeV, it is necessary in estimating the bremsstrahlung rate at low temperatures to take into account band st...
