The Imprint of Nova Nucleosynthesis in Presolar Grains

Open publisher page 1 citations

Abstract

Five silicon carbide and two graphite presolar grains, whose isotopic signatures point toward a nova origin, are described. In addition, theoretical isotopic ratios of several nuclear species, ranging from C to Si, computed with hydrodynamic models of nova outbursts, are shown. Such theoretical information can be useful for future identification of nova candidate grains.
