Neutrino Opacities at High Density and the Protoneutron Star Evolution
The early evolution of a protoneutron star depends both on the equation of state and neutrino interactions at high density. We identify the important sources of neutrino opacity and through model calculations show that in-medium effects play an important role in determining the neutrino mean free paths. The effects due to Pauli-blocking and many-body correlations due to strong interactions redu...
متن کاملProtoneutron Star Winds
Neutrino-driven winds are thought to accompany the Kelvin-Helmholtz cooling phase of nascent protoneutron stars in the first seconds after a core-collapse supernova. These outflows are a likely candidate as the astrophysical site for rapid neutron-capture nucleosynthesis (the rprocess). In this chapter we review the physics of protoneutron star winds and assess their potential as a site for the...
متن کاملProtoneutron star evolution and the neutrino driven wind in general relativistic neutrino radiation hydrodynamics simulations
Massive progenitor stars end their life in an explosion event with kinetic energies of the order 1051 erg. Behind the explosion ejecta, the low density and high entropy region formed immediately after the explosion is subject to neutrino heating. The neutrinos emitted from the remnant at the center, a protoneutron star (PNS), continually heat the material above the PNS surface. This heat is par...
متن کاملNeutrino Processes in Supernovae and the Physics of Protoneutron Star Winds
In preparation for a set of hydrodynamical simulations of core-collapse supernovae and protoneutron star winds, we investigate the rates of production and thermalization of νμ and ντ neutrinos in dense nuclear matter. Included are contributions from electron scattering, electron-positron annihilation, nucleon-nucleon bremsstrahlung, and nucleon scattering. We find that nucleon scattering domina...
متن کاملUsing cold atoms to measure neutrino mass
We propose a β-decay experiment based on a sample of ultracold atomic tritium. These initial conditions enable detection of the helium ion in coincidence with the β. We construct a two-dimensional fit incorporating both the shape of the β-spectrum and the direct reconstruction of the neutrino mass peak. We present simulation results of the feasible limits on the neutrino mass achievable in this...
