Fundamental parameters, integrated RGB mass loss and dust production in the Galactic globular cluster 47 Tucanae
Iain McDonald, Martha L. Boyer, Jacco Th. van Loon +12
Fundamental parameters and time-evolution of mass loss are investigated for post-main-sequence stars in the Galactic globular cluster 47 Tucanae (NGC 104). This is accomplished by…
LABOCA observations of giant molecular clouds in the south west region of the Small Magellanic Cloud
Caroline Bot, Monica Rubio, Francois Boulanger +8
The amount of molecular gas is a key for understanding the future star formation in a galaxy. Because H2 is difficult to observe directly in dense and cold clouds, tracers like CO…
Spitzer Analysis of HII Region Complexes in the Magellanic Clouds: Determining a Suitable Monochromatic Obscured Star Formation Indicator
Brandon Lawton, Karl D. Gordon, Brian Babler +18
HII regions are the birth places of stars, and as such they provide the best measure of current star formation rates (SFRs) in galaxies. The close proximity of the Magellanic Cloud…
The Mass-Loss Return From Evolved Stars to the LMC: Empirical Relations for Excess Emission at 8 and 24 μm
Sundar Srinivasan, Margaret Meixner, Claus Leitherer +18
We present empirical relations describing excess emission from evolved stars in the Large Magellanic Cloud (LMC) using data from the SAGE (Surveying the Agents of a Galaxy's Evolut…
Spatial variations of dust abundances across the Large Magellanic Cloud
Deborah Paradis, William T. Reach, Jean-Philippe Bernard +11
Using the data obtained with the Spitzer Space telescope as part of the Surveying the Agents of a Galaxy's Evolution (SAGE) legacy survey, we have studied the variations of the dus…
Surveying the Agents of Galaxy Evolution in the Tidally-Stripped, Low Metallicity Small Magellanic Cloud (SAGE-SMC) II. Cool Evolved Stars
Martha L. Boyer, Sundar Srinivasan, Jacco Th. van Loon +17
We investigate the infrared (IR) properties of cool, evolved stars in the Small Magellanic Cloud (SMC), including the red giant branch (RGB) stars and the dust-producing red superg…
Dust Production and Mass Loss in the Galactic Globular Cluster NGC 362
Martha L. Boyer, Iain McDonald, Jacco Th. van Loon +14
We investigate dust production and stellar mass loss in the Galactic globular cluster NGC 362. Due to its close proximity to the Small Magellanic Cloud (SMC), NGC 362 was imaged wi…
Surveying the Agents of Galaxy Evolution in the Tidally-Stripped, Low Metallicity Small Magellanic Cloud (SAGE-SMC). I. Overview
Karl D. Gordon, Margaret Meixner, Marilyn Meade +57
The Small Magellanic Cloud (SMC) provides a unique laboratory for the study of the lifecycle of dust given its low metallicity (~1/5 solar) and relative proximity (~60 kpc). This m…
