Description
Magnetorotational supernovae (MR-SNe) are promising candidates for the enrichment of heavy elements in the early universe. We analyze the nucleosynthesis of four sophisticated 3D (Obergaulinger & Aloy 2021) and two long evolved 2D neutrino-magnetohyrodynamic models (Aloy & Obergaulinger 2021). We identified three main mechanisms to synthesize heavy elements. Namely, an early and prompt ejection of matter, a late change of the protoneutron star morphology, and high entropies in the center of strong jets produced by the magnetorotational supernovae. Additionally, we estimated masses of unstable isotopes such as $^{56}$Ni. The obtained yields are in agreement with observed $^{56}$Ni masses of the most energetic supernovae, so called hypernovae.
