Spectroscopic monitoring of Southern Galactic O and WN stars: State of the Art in 2007
R. Gamen, R. Barba, N. Morrell +5
We are conducting a spectroscopic monitoring of O and WN -type stars in our Galaxy. In this work, we summarize some of our first results related to the search for radial-velocity v…
The Spitzer Survey of the Small Magellanic Cloud: Discovery of Embedded Protostars in the HII Region NGC 346
Joshua D. Simon, Alberto D. Bolatto, Barbara A. Whitney +6
We use Spitzer Space Telescope observations from the Spitzer Survey of the Small Magellanic Cloud (S3MC) to study the young stellar content of N66, the largest and brightest HII re…
ISOCAM Mid-infrared spectroscopy and NIR photometry of the HII complex N4 in LMC
A. Contursi, M. Rubio, M. Sauvage +3
[Abridged] We present the analysis of ISOCAM-CVF and NIR photometry data of the HII region complex N4 in LMC. The aim is twofold: 1) to study the connection between the ISM and the…
Pre-main sequence stars in the Lagoon Nebula (M8)
Julia I. Arias, Rodolfo H. Barba, Nidia I. Morrell
We report the discovery of new pre-main sequence (PMS) stars in the Lagoon Nebula (M8) at a distance of 1.25 kpc, based on intermediate resolution spectra obtained with the Boller…
Optical Spectroscopy of X-Mega targets in the Carina Nebula - VI. FO 15: a new O-Type double-lined eclipsing binary
V. S. Niemela, N. I. Morrell, E. Fernandez Lajus +3
We report the discovery of a new O-type double-lined spectroscopic binary with a short orbital period of 1.4 days. We find the primary component of this binary, FO 15, to have an a…
The infrared Hourglass cluster in M8
J. Arias, R. Barba, J. Maiz Apellaniz +2
A detailed study of the Hourglass Nebula in the M8 star forming region is presented. The study is mainly based on recent subarcsec-resolution JHKs images taken at Las Campanas Obse…
