OH/H2O/SiO/IR stellar masers
Abstract
The main infrared and radio properties of the stellar masers OH, H2O and SiO are reviewed. Maser emission in the three molecules is observed almost exclusively in M-type Miras with mean spectral types later than M5 and pulsation period greater than 200 days, semiregular variables, and M-supergiants of spectral types as early as M3.
