SUMMARY:Nucleosynthesis in magneto-rotational driven supernovae\, Netw
 ork in Neutrinos\, Nuclear Astrophysics\, and Symmetries (N3AS) Semina
 r\, Moritz Reichert \, TU – Darmstadt
DESCRIPTION:About half of the heavy elements in our Universe are synth
 esized by one process\, the rapid
\nneutron capture process (r-process
 ). This process requires extreme and violent environments
\nthat achie
 ve the necessary neutron-rich conditions. Therefore\, we use a modern 
 state of the art hydrodynamical simulation to investigate the
\nsynthe
 sis of elements in a possible host scenario of the r-process\, so-call
 ed magneto-rotational
\ndriven supernovae. In total\, we calculate the
  nucleosynthesis of four models with different
\nmagnetic field streng
 ths and rotation rates. The models host a variety of nucleosynthetic
\
 nconditions and synthesize neutron-rich\, but also small amounts of pr
 oton-rich isotopes. We
\nfind elements up to xenon (second r-process p
 eak) for the model with weakest magnetic field
\nstrength\, which is c
 aused by a late change of the proto-neutron star morphology. For the
\
 nmodel with the strongest magnetic field strength\, we find a fully op
 erating r-process. Having
\na detailed abundance pattern of this event
  calculated\, we discuss possible observables.
