Molecular Line Studies of Circumstellar Envelopes
This dissertation addresses several problems in the study of the dusty, gaseous envelopes commonly found around highly evolved stars. Most of the objects observed are M or N giants and are typically long-period variables. We also observed some objects with hotter central stars which may be young or forming planetary nebulae.
