Title: | Applications of precision astrometry to studies of massive YSOs | Authors: | Rioja, M. MOSCADELLI, Luca CESARONI, Riccardo |
Issue Date: | 2004 | Volume: | Proceedings of the 7th VLBI Network on New Developments in VLBI Science and Technology | Editors: | Bachiller, R.; Colomer, F.; Desmurs, J.-F.; de Vicente, P. | First Page: | 303 | Abstract: | We present VLBI observations of the H<SUB>2</SUB>O maser emission towards a selection of massive young stellar objects (YSOs). In one of these sources, IRAS20126+4104, the measured proper motions confirm that the H<SUB>2</SUB>O masers spots are tracing the very root (∼ 100 AU) of a conical bipolar outflow emerging near the position of the embedded YSO, and are an excellent tool to investigate the structure and kinematics of the outflow/jet. We also present preliminary results of a first epoch EVN observations of a selection of 5 high-mass YSO to assess the precise association of maser spots and molecular outflows in these sources.
