The Imprint of Nova Nucleosynthesis in Presolar Grains
Jordi Jose, Margarita Hernanz, Sachiko Amari +2
Infrared and ultraviolet observations of nova light curves have confirmed grain formation in their expanding shells that are ejected into the interstellar medium by a thermonuclear…

Could SiC A+B grains have originated in a post-AGB thermal pulse?
Falk Herwig, Sachiko Amari, Maria Lugaro +1
The carbon and nitrogen isotopic ratios of pre-solar SiC grains of type A+B suggest a proton-limited nucleosynthetic process as encountered, for instance, during the very late ther…

A New Astrophysical Interpretation of the Si and Ti Isotopic Compositions of Mainstream SiC Grains from Primitive Meteorites
Maria Lugaro, Roberto Gallino, Maurizio Busso +2
Mainstream presolar SiC grains from primitive meteorites show a clear s-process signature in the isotopic composition of heavy trace elements. These grains most likely condensed in…
