The VMC survey -- XXXVI. Young stellar variability in the Large Magellanic Cloud
Viktor Zivkov, Joana M. Oliveira, Monika G. Petr-Gotzens +11
Studies of young stellar objects (YSOs) in the Galaxy have found that a significant fraction exhibit photometric variability. However, no systematic investigation has been conducte…
The VMC Survey -- XXXV. Model fitting of LMC Cepheid light curves
Fabio Ragosta, Marcella Marconi, Roberto Molinaro +10
We present the results of the light curve model fitting technique applied to optical and near-infrared photometric data for a sample of 18 Classical Cepheids (11 fundamentals and 7…
A dearth of OH/IR stars in the Small Magellanic Cloud
Steven R. Goldman, Jacco Th. van Loon, José F. Gómez +7
We present the results of targeted observations and a survey of 1612-, 1665-, and 1667-MHz circumstellar OH maser emission from asymptotic giant branch (AGB) stars and red supergia…
The SAGE-Spec Spitzer Legacy program: The life-cycle of dust and gas in the Large Magellanic Cloud. Point source classification III
Olivia C. Jones, Paul M. Woods, F. Kemper +16
The Infrared Spectrograph (IRS) on the {\em Spitzer Space Telescope} observed nearly 800 point sources in the Large Magellanic Cloud (LMC), taking over 1,000 spectra. 197 of these…
Dusty OB stars in the Small Magellanic Cloud - II: Extragalactic Disks or Examples of the Pleiades Phenomenon?
Joshua J. Adams, Joshua D. Simon, Alberto D. Bolatto +6
We use mid-infrared Spitzer spectroscopy and far-infrared Herschel photometry for a sample of twenty main sequence O9--B2 stars in the Small Magellanic Cloud (SMC) with strong 24 m…
Dusty OB Stars in the Small Magellanic Cloud - I: Optical Spectroscopy Reveals Predominantly Main-Sequence OB Stars
Holly A. Sheets, Alberto D. Bolatto, Jacco Th. van Loon +4
We present the results of optical spectroscopic follow-up of 125 candidate main sequence OB stars in the Small Magellanic Cloud (SMC) that were originally identified in the S3MC in…
The VMC Survey. II. A multi-wavelength study of LMC planetary nebulae and their mimics
B. Miszalski, R. Napiwotzki, M. -R. L. Cioni +3
The VISTA Magellanic Cloud (VMC) survey is assembling a deep, multi-epoch atlas of YJKs photometry across the Magellanic Clouds. Prior to the VMC survey only the brightest Magellan…
Debris discs in the 27 Myr old open cluster IC4665
Rachel Smith, Rob Jeffries, Joana Oliveira
We present Spitzer IRAC and MIPS 24um imaging of members of the 27+/-5Myr old open cluster IC 4665. Models for the assembly of terrestrial planets through planetesimal collisions a…
The youngest massive protostars in the Large Magellanic Cloud
M. Sewilo, R. Indebetouw, L. R. Carlson +19
We demonstrate the unique capabilities of Herschel to study very young luminous extragalactic young stellar objects (YSOs) by analyzing a central strip of the Large Magellanic Clou…
Timescale of Mass Accretion in Pre-Main-Sequence Stars
D. Fedele, M. E. van den Ancker, Th. Henning +2
We present initial result of a large spectroscopic survey aimed at measuring the timescale of mass accretion in young, pre-main-sequence stars in the spectral type range K0 - M5. U…
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…
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…
