This research aims to investigate how neutrino-driven explosions influence nucleosynthesis yields across various progenitor stars.
Analyzed explosion properties from three stellar evolution codes: FRANEC, KEPLER, and MESA.
Employed the GR1D+ neutrino-driven core-collapse supernova code for simulations.
Carried out post-processing with the SkyNet code to calculate nucleosynthetic yields.
1D+ simulations yielded explosion energies and remnant masses consistent with observed type II-P, IIb, and Ib supernovae.
More realistic neutrino-driven explosions resulted in different yields compared to simple bomb and piston models.
Piston and bomb models artificially increased production of Fe-peak elements, while different explodabilities affected lighter elements.
