摘要：

Meteoritic silicon carbide grains, formed in the winds from carbon stars, contain noble gases and other species whose elemental and isotopic abundances are a probe of stellar nucleosynthesis. Theoretical models of carbon stars can explain a variety of measured abundances, in particular the range of krypton isotope ratios and the excess 22Ne found in the grains. © 1990 Nature Publishing Group.
