Neutrino-pair emission due to electron-phonon scattering in a neutron star crust
نویسنده
چکیده
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 nuclear composition for body-centered-cubic and face-centered-cubic Coulomb crystals. The results are fitted by a unified analytic expression. A comparison is given of the neutrino bremsstrahlung energy losses in a neutron star crust composed of ground state and accreted matter, in the solid and liquid phases.

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)...

We study the emission of neutrinos, resulting from the scattering of electrons off magnetic flux tubes (fluxoids) in the neutron star cores with superfluid (superconducting) protons. In the absence of proton superfluidity (T ≥ Tcp), this process transforms into the well known electron synchrotron emission of neutrino pairs in a locally uniformmagnetic fieldB, with the neutrino energy loss rate ...

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...
