Infrared Stars with Strong 1665-1667-MHz OH Microwave Emission.
Abstract
Microwave and infrared observations are presented of seven stars that have strong infrared and 1665/1667-MHz main-line OH emission. The sources were selected because the 1665/1667-MHz OH emission is stronger than the 1612-MHz OH emission. Five of thses sources have associated H2O microwave emission. The sources are associated with M-type, long-period variable stars and generally show only a small, excess infrared radiation from 3 to 20 micrometers above that expected from the photosphere. The data indicate that both 1665/1667-MHz and 1612-MHz stars form a continuous sequence in their intrinsic OH luminosities and their infrared properties. (Author)
