Title: Chemistry in the circumstellar envelopes around mass-losing red giants
Abstract: When low and intermediate mass stars evolve off the main sequence, they become red giants. During the first ascent up the red giant branch, the stars lose mass at a relatively modest rate (∼10−9 M⊙ yr−1. Dupree (1986)). However, during the second ascent up the red giant branch, the asymptotic giant branch (AGB), stars lose mass at a much greater rate; up to 10−4 M⊙ yr−1 (Zuckerman 1980, Jura 1986a, Olofsson 1985). These outflows from AGB stars are very cold (T < 1000 K), and they contain large amounts of dust and molecules. The chemistry in these outflows is the topic of this chapter (see also Olofsson (1987), Omont (1987), Millar (1988)).
