[4.12] Water Masers and YSOs in H~II Regions - A Continuing Survey

K. R. Healy (Arizona State University), M. J. Claussen (NRAO), J. J. Hester (Arizona State University)

We present the results of a second year of our search for water maser emission associated with young low-mass stars in four H~II regions --- M16, M20, S125, and NGC~6357 --- conducted with the NRAO Very Large Array during March and May 2001. We report the detection of 5 new masers in M16 and M20. The two new M16 masers are at positions of molecular gas bordering the H~II region to the north and to the east of the cluster NGC~6611. The three new M20 masers are clustered around the position of the massive core TC3, southwest of the H~II region center. We detected no maser emission from S125 or NGC~6357. We present the positions and spectra of the new masers in M16 and M20, as well as present new spectra for the two M16 masers we detected last year.
