Potential Effects of Fast Neutrino Flavor Transformations on Neutrino-Driven Wind and Supernova Nucleosynthesis
Time: 3:30 pm
Place: https://berkeley.zoom.us/j/91922781599
Speaker: Andre Sierverding , University of Minnesota
Abstract: Recently, the possibility that fast neutrino flavor transformations may occur very close to the core of a collapsing massive star has received a lot of
attention. Such transformations would affect the conditions of the wind driven by the intense neutrino emission from a proto-neutron star (PNS) where nuclei
heavier than Fe can be produced. We show that flavor transformations would lead to more proton-rich outflows and more favorable conditions for a nu-p process
to occur. Similarly, the conditions of the innermost, neutrino-heated supernova ejecta would also be affected and I illustrate possible effects with nucleosynthesis
calculations based on a 3D supernova model.
