| There are many uncertainties in our understanding of core-collapse supernovae, including the explosion mechanism and nucleosynthesis. One way to gain insight into these phenomena is to study the nucleosynthesis of radioactive isotopes in the shock-heated material. These isotopes, such as <sup>44</sup>Ti and <sup>56</sup>Ni, determine the features of the supernova light curve. Observations of supernova remnants can be used to put bounds on the production of these isotopes. | There are many uncertainties in our understanding of core-collapse supernovae, including the explosion mechanism and nucleosynthesis.
