Neutrino scattering in strong magnetic fields∗
Neutrino interactions in strong magnetic fields have gained a lot of attention because of the problem of neutrino emission from a proto-neutron star. It has been argued that a small asymmetry in the neutrino emission can explain the high peculiar velocities of pulsars. Based on earlier work[1] on neutrino dispersion relations in an external magnetic field, it has been shown[2] that neutrino osc...
متن کاملNeutrino Processes in Strong Magnetic Fields
The processes νe +n ⇋ e− + p and ν̄e + p ⇋ e +n provide the dominant mechanisms for heating and cooling the material below the stalled shock in a core-collapse supernova. We summarize the major effects of strong magnetic fields on the rates of the above reactions and illustrate these effects with a simple supernova model. Due to parity violation of weak interaction the heating rates are asymmetr...

Neutrino-driven winds and nucleosynthesis
Baryonic outflows from proto-neutron stars formed in core-collapse supernova explosions are one of the possible scenarios for the production of heavy elements via the r-process. If the ejected matter reaches supersonic velocities the outflow is known as neutrino-driven wind. We have studied the long-time evolution of proto-neutron stars with oneand two-dimensional hydrodynamical simulations and...
متن کاملPlasma dynamics in pulsed strong magnetic fields
Recent investigations of the interaction of fast-rising magnetic fields with multi-species plasmas at densities of 10– 10 cm are described. The configurations studied are planar or coaxial interelectrode gaps pre-filled with plasmas, known as plasma opening switches. The diagnostics are based on time-dependent, spatially resolved spectroscopic observations. Three-dimensional spatial resolution ...
