Nucleosynthetic signatures of asymmetric supernovae - Lessons from 1-dimensional explosions

We review the evidence for asymmetries in explosions, and in particular, the nucleosynthetic signatures from these asymmetries. To guide our intuition for these yields, we have modeled a series of spherically symmetric explosions with a range of explosion energies. Here we present the results from these 1-dimensional simulations, focusing on the yields of the radioactive elements ⁴⁴Ti and ⁵⁶Ni. We find that, although the abundance yields of ⁴⁴Ti do depend sensitively on the explosion energy, the trend (whether it increases or decreases with explosion energy) depends very sensitively on the model.
