Ledoux Convection in Protoneutron Stars—A Clue to Supernova Nucleosynthesis?
Two-dimensional hydrodynamical simulations of the deleptonization of a newly formed neutron star (NS) were performed. Driven by negative lepton fraction and entropy gradients, convection starts near the neutrinosphere about 20-30 ms after core bounce but moves deeper into the protoneutron star (PNS), and after about 1 s the whole PNS …
