Title: Neutrino emission, equation of state and the role of strong gravity

Abstract

Neutron-star mergers are interesting for several reasons: they are proposed as the progenitors of short gamma-ray bursts, they have been speculated to be a site for the synthesis of heavy elements, and they emit gravitational waves possibly detectable at terrestrial facilities. The understanding of the merger process, from the pre-merger stage to the final compact object-accreting system involves detailed knowledge of numerical relativity and nuclear physics. In particular, key ingredients for the evolution of the merger are neutrino physics and the matter equation of state. We present some aspects of neutrino emission from binary neutron star mergers showing the impact that the equation of state has on neutrinos and discuss some spectral quantities relevant to their detection such as energies and luminosities far from the source.

  • The neutrino emission in a magnetic field should have an angular asymmetry because of magnetobremsstrahlung, photonuclear processes, and other processes. Certain objects may undergo an intense self-acceleration, as has been discussed elsewhere.
  • Estimates are obtained for the maximum momentum that could be imparted to a collapsing star because of the anisotropic emission of neutrinos when free nucleons undergo Urca processes at high temperatures and densities in a strong magnetic field.
  • The probability of neutron beta decay in the presence of degenerate magnetized matter consisting of electrons, protons, and neutrons is calculated by using exact solutions to the Dirac equation for charged particles in a uniform magnetic field. The asymmetry of the angular distribution of the momentum carried away by product antineutrinos is studied with allowance for the effect of a strong magnetic field. The values of basic parameters (magnetic-field strength, matter density, and matter temperature) that affect the reaction being considered are chosen in such a way as to render this investigation applicable to an analysis of the cooling ofmore » a neutron star.« less
  • The emission of {nu}{nu} pairs off electrons in a polarized ultraintense electromagnetic (e.g., laser) wave field is analyzed. We elaborate on the significance of nonlinear electrodynamics effects (i.e., multiphoton processes) and the peculiarities of neutrino production. Special attention is devoted to the convergence of the reaction probabilities as a function of the number of absorbed photons. Expressions for large field intensities are provided. The asymmetry between the probabilities of electron and {mu}+{tau} neutrino production depends on initial conditions such as energy of the wave field photons and the field intensity. These findings differ from the lowest-order perturbative calculation of themore » reaction {gamma}+e{yields}e{sup '}+{nu}{nu}.« less
