presolar sic of type a+b: grains of an enigmatic originN, Al, and Si isotopic ratios differ between presolar SiC grains of type A ( C-12/C-13 < 3.5) and type B (3.5 < C-12/C-13 < 10). J and CH stars are promising sources but the lack of astronomical data and theoretical models limit the identification of these sources.
