Network in Neutrinos, Nuclear Astrophysics, and Symmetries (N3AS) Seminar
Nucleosynthesis in magneto-rotational driven supernovae
Time: 2:00 pm
Place: https://berkeley.zoom.us/j/91922781599
Speaker: Moritz Reichert , TU – Darmstadt
Abstract: About half of the heavy elements in our Universe are synthesized by one process, the rapid neutron capture process (r-process). This process requires extreme and violent environments that achieve the necessary neutron-rich conditions. Therefore, we use a modern state of the art hydrodynamical simulation to investigate the synthesis of elements in a possible host scenario of the r-process, so-called magneto-rotational driven supernovae. In total, we calculate the nucleosynthesis of four models with different magnetic field strengths and rotation rates. The models host a variety of nucleosynthetic conditions and synthesize neutron-rich, but also small amounts of proton-rich isotopes. We find elements up to xenon (second r-process peak) for the model with weakest magnetic field strength, which is caused by a late change of the proto-neutron star morphology. For the model with the strongest magnetic field strength, we find a fully operating r-process. Having a detailed abundance pattern of this event calculated, we discuss possible observables.
