Infrared Observations of Large Amplitude Pulsating Stars
Patricia A. Whitelock
Abstract
Our understanding of large amplitude pulsating stars and their status in stellar evolution is briefly reviewed. The paper then describes the near-infrared light curves of various asymptotic giant branch stars, concentrating on possible evidence for changing mass-loss rates. The stars discussed include oxygen- and carbon-rich Miras, OH/IR stars, thick-shelled carbon stars and symbiotic Miras. Finally a newly discovered Mira variable in the Sagittarius Dwarf Galaxy is described.
