OH and H 2O Observations of Cold IRAS Stars
Abstract
The results of OH and H20 maser observations of a complete sample of IRAS objects with infrared colors similar to those of the coldest circumstellar dust/gas envelopes are presented. The color sequence of AGB stars on the IRAS color-color diagram is discussed. Evidence that the reddest objects on the sequence are the most massive is examined.
