The presence of an excess of short-lived radionuclides in the early protoplanetary disk has been inferred from studying how the distribution of the abundances, in materials like Ca-Al-rich inclusions, differ from the solar abundance distribution (SAD). The likely source of these radioactivites is a supernova that ejected material into the early solar system. This thesis will discuss the solar abundance distribution and how a supernova may have contributed a 'late addition' of material into the early solar system. In addition, we have constructed online resources for studying these topics. This thesis will outline the Solar Abundance Tool, which allows a user to study the details of the solar abundance distribution, and the 1d Stellar Ejecta Module, which simulates a simplistic approach to the question of late additions.
