Masers Around Young Stars
Young star forming regions are often associated with H₂O masers, and occasionally with SiO masers, and radio VLBI can trace the spatial and kinematic distribution of the emission. In collaboration with Lincoln Greenhill, James Herrnstein, James Moran, and Karl Menten, I have mapped the H₂O and SiO masers in the W51 high-mass star forming region, and find that the maser emission appears to trace an outflow from an obscured high-mass protostar (Eisner et al. 2002). Recently, we conducted a search for H₂O maser emission associated with young stars with the Green Bank Telescope, and plan to follow up new detections at higher angular resolution.
