Silicon and Carbon Isotopic Ratios in AGB Stars: SiCGrain Data, Models, and the Galactic Evolution of the Si Isotopes

Zinner, Ernst; Nittler, Larry R; Gallino, Roberto; Karakas, Amanda; Lugaro, Maria Anna; Straniero, O; Lattanzio, John


Presolar SiC grains of the mainstream, Y, and Z type are believed to come from carbon stars. We compared their C and Si isotopic ratios with theoretical models for the envelope compositions of AGB stars. Two sets of models (FRANEC and Monash) use a range
