Internal Dynamics of the Hypercompact H II Region G28.20-0.04N
M. Sewilo, E. Churchwell, S. Kurtz +2
High resolution (0.15") Very Large Array observations of 7 mm continuum and H53a line emission toward the hypercompact H II region G28.20-0.04N reveal the presence of large-scale o…
An H2CO 6cm Maser Pinpointing a Possible Circumstellar Torus in IRAS18566+0408
E. Araya, P. Hofner, M. Sewilo +7
We report observations of 6cm, 3.6cm, 1.3cm, and 7mm radio continuum, conducted with the Very Large Array towards IRAS18566+0408, one of the few sources known to harbor H2CO 6cm ma…
A Review of H2CO 6cm Masers in the Galaxy
E. Araya, P. Hofner, W. M. Goss
We present a review of the field of formaldehyde (H2CO) 6cm masers in the Galaxy. Previous to our ongoing work, H2CO 6cm masers had been detected in the Galaxy only toward three re…
Ultra-Compact H II Regions and the Early Lives of Massive Stars
M. G. Hoare, S. E. Kurtz, S. Lizano +2
We review the phenomenon of ultra-compact H II regions (UCHIIs) as a key phase in the early lives of massive stars. This most visible manifestation of massive star formation begins…
Water Masers Toward Ultracompact HII Regions
S. Kurtz, P. Hofner
We present a survey in the 6_{16}-5_{23} rotational water transition toward 33 galactic ultracompact HII regions. Maser emission is detected toward 18 of these sources; two are new…
The G9.62+0.19-F Hot Molecular Core - The infrared view on very young massive stars
Hendrik Linz, Bringfried Stecklum, Thomas Henning +2
(abridged) We present the results of an extensive infrared study of the massive star-forming region G9.62+0.19. The data cover information from broad- and narrow-band filters in th…
