Issue Date: | 2004 | Journal: | MEMORIE DELLA SOCIETA ASTRONOMICA ITALIANA | Volume: | 48th Annual Meeting of the Italian Astronomical Society, I Colori dell'Universo | Editors: | Wolter, A.; Israel, G. L.; Bacciotti, F. | Number: | 5 | First Page: | 123 | Abstract: | We have conducted Very Long Baseline Interferometry (VLBI) observations of the 22.2 GHz water masers towards three massive star forming regions. With three observing epochs, few distinct maser features were detected for each source. For features persistent in time, accurate values of the proper motions are derived. A preliminary analysis indicates that the kinematics traced by water masers is consistent with expanding motions, possibly driven by wide-angle winds. | Conference Name: | 48th Annual Meeting of the Italian Astronomical Society, I Colori dell'Universo | Conference Place: | Milano, Italy | Conference Date: | April 19-23, 2004 | URI: | http://hdl.handle.net/20.500.12386/32830 | URL: | http://sait.oat.ts.astro.it/MSAIS/5/index.html | ISSN: | 0037-8720 | Bibcode ADS: | 2004MSAIS...5..123G | Fulltext: | open |
