6. OH Masers in Star-Forming Regions
Part of the Lecture Notes in Physics book series (LNP, volume 412)

Abstract

OH masers are a potentially powerful probe of the physical conditions in massive star-forming regions, giving detailed information on the kinetic and dust temperatures, number densities of H2 and OH, bulk flows and magnetic fields in, the vicinity of massive young stellar objects. Using current theories and data, we describe how bright maser spots, as seen in VLBI at 18cm, 6 cm and 5 cm , may arise and we outline the physical conditions which may be associated with masers at different frequencies.
