Description
The astrophysical origin of the heavy neutron-deficient isotopes, commonly referred to as p-nuclei, remains one of the major open problems in Nuclear Astrophysics. Among the proposed production sites, Core-Collapse Supernovae (CCSNe) are considered one of the most promising environments for their nucleosynthesis. In this presentation, I will discuss the current results of my PhD research, based on the analysis of a CCSN explosion model of a 20 M⊙ star with solar metallicity. I will highlight the ejecta trajectories that play the most significant role in p-nuclei production and examine the influence of radioactive isotopes and their decay chains on the resulting abundance patterns.
