Molecular jets and H2O masers in the AFGL 5142 hot core.
HUNTER T.R., TESTI L., ZHANG Q. and SRIDHARAN T.K.
Abstract (from CDS):
The 22 GHz H2O masers most closely associated with the central object have undergone substantial variability in flux and position during three epochs spread over eight years. In addition, two new water maser features have been detected significantly offset (3"-4", 0.03 pc) from the centimeter continuum peak position. One of these maser features exhibits a linear structure of spots with spatial-kinematic evidence for a rotating circumstellar disk of radius 40 AU and dynamical mass of ~1 M☉. The other is found to be associated with a near-infrared source with large infrared excess. In addition to the 28 embedded stars previously seen in infrared images, we conclude that this cluster is concurrently forming both low- and high-mass stars.
