Issue Date: | 2008 | Volume: | Massive Star Formation: Observations Confront Theory | Editors: | Beuther, Henrik; Linz, Hendrik; Henning, Thomas | Series: | ASTRONOMICAL SOCIETY OF THE PACIFIC CONFERENCE SERIES | Number: | 387 | First Page: | 71 | Abstract: | We present evidence of infall in a circumstellar rotating toroid enshrouding a luminous star in the massive star-forming region G24.78+0.08. Besides being one of the rare direct detections of infall in a young high-mass star, our finding stands unique for the simultaneous presence of three elements in the same massive object: a rotating, collapsing toroid, a bipolar outflow, ejected along the rotation axis, and a hypercompact ionized H II region. The large accretion rate and the existence of a hypercompact H II region confirm that the accretion cannot be spherically symmetric and must occur in a circumstellar disk. | Conference Name: | Massive Star Formation: Observations Confront Theory | Conference Place: | Heidelberg, Germany | Conference Date: | 10-14 September, 2007 | URI: | http://hdl.handle.net/20.500.12386/32798 | URL: | https://aspbooks.org/a/volumes/article_details/?paper_id=28257 | ISSN: | 1050-3390 | Bibcode ADS: | 2008ASPC..387...71B | Fulltext: | open |
