The Stellar Content of Obscured Galactic Giant HII Regions. VI: W51A
E. Figueredo, R. D. Blum, A. Damineli +2
We present K-band spectra of newly born OB stars in the obscured Galactic giant H II region W51A and ~ 0.8'' angular resolution images in the J, H and K_S-bands. Four objects have…
Chandra X-ray Observations of the Young Stellar Cluster NGC 6193 in the Ara OB1 Association
S. L. Skinner, S. A. Zhekov, F. Palla +1
A 90 ks Chandra HETG observation of the young stellar cluster NGC 6193 in the southern Ara OB1 association detected 43 X-ray sources in a 2' x 2' core region centered on the young…
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…
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…
