Oh and H/sub 2/O masers in the Monoceros-R2 molecular cloud
Technical Report
·
OSTI ID:7362312
Emission from OH and H/sub 2/O masers has been detected in the direction of the Monoceros-R2 molecular cloud. Only the 1612 and 1665 MHz OH lines are observed, and from the emission characteristics of the sources the authors conclude that they arise in different locations. Two velocity components of the 1665 MHz source are highly linearly polarized (about 100%). This result allows the determination of limits on the magnetic field strength in the emission region, 3 x 10/sup -6/ << B << 4 x 10/sup -4/ Gauss, and to estimate its orientation. The relation of the maser emission to the embedded HII region and to the ir sources in this cloud is discussed. The Mon-R2 region is similar to the Orion nebula complex, and appears to represent a somewhat earlier stage of star formation. (GRA)
