Early-stage young stellar objects in the Small Magellanic Cloud
J. M. Oliveira, J. Th. van Loon, G. C. Sloan +12
We present new observations of 34 YSO candidates in the SMC. The anchor of the analysis is a set of Spitzer-IRS spectra, supplemented by groundbased 3-5 micron spectra, Spitzer and…
On the metallicity dependence of crystalline silicates in oxygen-rich asymptotic giant branch stars and red supergiants
O. C. Jones, F. Kemper, B. A. Sargent +10
We investigate the occurrence of crystalline silicates in oxygen-rich evolved stars across a range of metallicities and mass-loss rates. It has been suggested that the crystalline…
Carbon-rich dust production in metal-poor galaxies in the Local Group
G. C. Sloan, M. Matsuura, E. Lagadec +7
We have observed a sample of 19 carbon stars in the Sculptor, Carina, Fornax, and Leo I dwarf spheroidal galaxies with the Infrared Spectrograph on the Spitzer Space Telescope. The…
The Kilometer-Sized Main Belt Asteroid Population as Revealed by Spitzer
Erin Lee Ryan, Donald R. Mizuno, Sachindev S. Shenoy +5
Multi-epoch Spitzer Space Telescope 24 micron data is utilized from the MIPSGAL and Taurus Legacy surveys to detect asteroids based on their relative motion. These infrared detecti…
Globules and pillars seen in the [CII] 158 micron line with SOFIA
N. Schneider, R. Güsten, P. Tremblin +22
Molecular globules and pillars are spectacular features, found only in the interface region between a molecular cloud and an HII-region. Impacting Far-ultraviolet (FUV) radiation c…
Photoevaporating Proplyd-like objects in Cygnus OB2
Nicholas J. Wright, Jeremy J. Drake, Janet E. Drew +4
We report the discovery of ten proplyd-like objects in the vicinity of the massive OB association Cygnus OB2. They were discovered in IPHAS H-Alpha images and are clearly resolved…
