Abstract:

The characteristics of OH emission sources associated with late M-type variable stars are discussed. A total of 456 IR stars and 18 other objects were surveyed and OH emission was detected from 25 IR stars. Including four OH sources discovered by other observers, there are 29 OH emission sources associated with IR stars. In addition there are 8 OH sources which have OH emission characteristics similar to the OHIR stars but for which no IR star has yet been detected. Based on their OH, IR and visual properties, the OHIR stars can be divided into three groups. The group of OHIR stars 19 stars with their OH emission strongest at 1612 MHz and concentrated in two narrow velocity ranges is discussed in this paper. Author
