Chemical depletion in the Large Magellanic Cloud: RV Tauri stars and the photospheric feedback from their dusty discs
C. Gielen, H. Van Winckel, M. Reyniers +11
Aims: By studying the photospheric abundances of 4 RV Tauri stars in the LMC, we test whether the depletion pattern of refractory elements, seen in similar Galactic sources, is als…
A Spitzer Space Telescope far-infrared spectral atlas of compact sources in the Magellanic Clouds. I. The Large Magellanic Cloud
Jacco Th. van Loon, Joana M. Oliveira, Karl D. Gordon +10
[abridged] We present 52-93 micron spectra obtained with Spitzer in the MIPS-SED mode, of a representative sample of luminous compact far-IR sources in the LMC. These include carbo…
Far-Ultraviolet Dust Albedo Measurements in the Upper Scorpius Cloud Using the SPINR Sounding Rocket Experiment
N. K. Lewis, T. A. Cook, K. P. Wilton +3
The Spectrograph for Photometric Imaging with Numeric Reconstruction (SPINR) sounding rocket experiment was launched on 2000 August 4 to record far-ultraviolet (912-1450 A) spectra…
Star-Forming or Starbursting? The Ultraviolet Conundrum
M. Boquien, D. Calzetti, R. Kennicutt +6
Compared to starburst galaxies, normal star forming galaxies have been shown to display a much larger dispersion of the dust attenuation at fixed reddening through studies of the I…
Warm and Dense Molecular Gas in the N159 Region: 12CO J=4-3 and 13CO J=3-2 Observations with NANTEN2 and ASTE
Yoji Mizuno, Akiko Kawamura, Toshikazu Onishi +29
New 12CO J=4-3 and 13CO J=3-2 observations of the N159 region in the Large Magellanic Cloud have been made. The 12CO J=4-3 distribution is separated into three clumps. These new me…
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…
FUSE Measurements of Far-Ultraviolet Extinction. III. The Dependence on R(V) and Discrete Feature Limits from 75 Galactic Sightlines
Karl D. Gordon, Stefan Cartledge, Geoffrey C. Clayton
We present a sample of 75 extinction curves derived from FUSE far-ultraviolet spectra supplemented by existing IUE spectra. The extinction curves were created using the standard pa…
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…
Spitzer SAGE Infrared Photometry of Massive Stars in the Large Magellanic Cloud
A. Z. Bonanos, D. L. Massa, M. Sewilo +11
We present a catalog of 1750 massive stars in the Large Magellanic Cloud, with accurate spectral types compiled from the literature, and a photometric catalog for a subset of 1268…
Spitzer Observations of Cold Dust Galaxies
C. N. A. Willmer, G. H. Rieke, Emeric Le Floc'h +4
We combine new Spitzer Space Telescope observations in the mid- and far-infrared with SCUBA 850 micron observations to improve the measurement of dust temperatures, masses and lumi…
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…
Spitzer View of Young Massive Stars in the LMC HII Complex N44
C. -H. Rosie Chen, You-Hua Chu, Robert A. Gruendl +2
The HII complex N44 in the Large Magellanic Cloud (LMC) provides an excellent site to perform a detailed study of star formation in a mild starburst, as it hosts three regions of s…
