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…
Gemini Mid-Infrared Imaging of Massive Young Stellar Objects in NGC 3576
C. L. Barbosa, A. Damineli, R. D. Blum +1
We present a mid-infrared study of NGC 3576. The high-resolution images were taken at the Gemini South Observatory through narrow and broad band filters centered between 7.9 micron…
MSX Mid infrared imaging of massive star birth environments. II: Giant HII regions
Peter S Conti, Paul A. Crowther
We conduct a Galactic census of Giant HII regions, based on the all sky 6cm dataset of Kuchar & Clark, plus the kinematic distances obtained by Russeil. From an inspection of mid-I…
