Asymptotic giant branch grains from

Most presolar silicon carbide and oxide grains and a significant fraction of presolar silicate grains found in meteorites come from low- to intermediate-mass stars in the asymptotic giant branch (AGB) phase (see Chapter 3). Evidence for this conclusion derives from two sources (1) spectroscopic observations of the envelopes of these stars and (2) comparison... [Pg.132]

AGB star asymptotic giant branch star, a cool and luminous red giant star. These evolved stars drive an intense wind that removes material from the surface at an increasing rate as the end of its lifecyle approaches. AGB stars are the proposed source of many types of presolar grains. [Pg.349]
