Isolated Wolf-Rayet Stars and O Supergiants in the Galactic Center Region Identified via Paschen-alpha Excess
Jon Mauerhan, Angela Cotera, Hui Dong +4
We report the discovery of 19 hot, evolved, massive stars near the Galactic center region (GCR). These objects were selected for spectroscopy owing to their detection as strong sou…
HST Palpha Survey of the Galactic Center -- Searching the missing young stellar populations within the Galactic Center
H. Dong, Q. D. Wang, A. Cotera +6
We present preliminary results of our \hst Pa survey of the Galactic Center (\gc), which maps the central 0.650.25 degrees around Sgr A*. This survey provides us with a…
Extinction toward the Compact HII Regions G-0.02-0.07
E. A. Mills, M. R. Morris, C. C. Lang +4
The four HII regions in the Sgr A East complex: A, B, C, and D, represent evidence of recent massive star formation in the central ten parsecs. Using Paschen-alpha images taken wit…
HST/NICMOS Paschen-alpha Survey of the Galactic Center: Overview
Q. D. Wang, H. Dong, A. Cotera +6
We have recently carried out the first wide-field hydrogen Paschen-alpha line imaging survey of the Galactic Center (GC), using the NICMOS instrument aboard the Hubble Space Telesc…
First Spectroscopic Identification of Massive Young Stellar Objects in the Galactic Center
Deokkeun An, Solange V. Ramírez, Kris Sellgren +7
We report the detection of several molecular gas-phase and ice absorption features in three photometrically-selected young stellar object (YSO) candidates in the central 280 pc of…
HST/NICMOS Observations of the Embedded Cluster in NGC 2024: Constraints on the IMF and Binary Fraction
Wilson M. Liu, Michael R. Meyer, Angela S. Cotera +1
We present an analysis of NICMOS observations of the embedded cluster associated with NGC 2024. An analysis of the cluster color-magnitude diagram (CMD) using the models of D'Anton…
