Detection of H2O Maser Emission from Four Infrared Sources,

Abstract

Maser emission from interstellar water vapor has been found towards four infrared sources: OMC-2, OH231.8+4.2 (also known as OH0739-14), S140-IR and Monoceros R2. Three of these new maser sources appear to be situated in active sites of star formation, while the unusual source OH231.8+4.2 is more likely to be related to a late-type stellar object. The line profiles are relatively simple, showing at most a few velocity components, some of which vary with a time scale as short as a few weeks. The individual sources are discussed in detail.
