Abstract

In the last decade, presolar grains have been isolated from primitive meteorites and have been extensively studied. Presolar grains show extreme isotopic anomalies, which provide convincing evidence that they originate from stars. Their isotopic composition can provide information and constraints on nucleosynthesis in stars and on processes in supernova (SN) explosions. For example, isotopic features of SN grains (SiC type X, low-density graphite grains, Si₃N₄) can only be explained if SN ejecta undergo extensive heterogeneous mixing during the explosion.
