Near-Infrared Spectroscopy of Ultracompact \ion{H}{2} regions in W51A with NIFS/ALTAIR
Cassio L. Barbosa, Felipe Navarete, Robert D. Blum +1
W51A is the most active star formation region of the Giant \ion{H}{2} region W51. It harbors the two massive proto-clusters W51e and W51\,IRS2, which are very rare in the Galaxy. W…
Massive star formation and feedback in W49A: The source of our Galaxy's most luminous water maser outflow
Nathan Smith, Barbara A. Whitney, Peter S. Conti +2
We present high spatial resolution mid-IR images of the ring of UCHII regions in W49A obtained at Gemini North, allowing us to identify the driving source of its powerful H2O maser…
High Spatial Resolution Spectroscopy of W51 IRS2E and IRS2W: Two Very Massive Young Stars in Early Formation Stages
C. L. Barbosa, R. D. Blum, P. S. Conti +2
We present -band spectra of the near infrared counterparts to IRS2E and IRS2W which is associated with the ultracompact HII region W51d, both of them embedded sources in the Gal…
On the role of the WNH phase in the evolution of very massive stars: Enabling the LBV instability with feedback
Nathan Smith, Peter S. Conti
(abridged) We propose the new designation ``WNH'' for luminous Wolf-Rayet (WR) stars of the nitrogen sequence with H in their spectra. These are commonly called WNL stars (e.g., WN…
Accretion Signatures from Massive Young Stellar Objects
R. D. Blum, C. L. Barbosa, A. Damineli +2
High resolution (lambda / Delta-lambda = 50,000) K-band spectra of massive, embedded, young stellar objects are presented. The present sample consists of four massive young stars l…
Australia Telescope Compact Array Survey of Candidate Ultra-Compact and Buried HII Regions in the Magellanic Clouds
Remy Indebetouw, Kelsey E. Johnson, Peter Conti
We present a systematic survey for ultracompact HII (UCHII) regions in the Magellanic Clouds. Understanding the physics of massive star formation (MSF) is a critical astrophysical…
