Spitzer Infrared Spectrographic point source classification in the Small Magellanic Cloud
Paul M. E. Ruffle, F. Kemper, O. C. Jones +16
The Magellanic clouds are uniquely placed to study the stellar contribution to dust emission. Individual stars can be resolved in these systems even in the mid-infrared, and they a…
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…
Identification of Spitzer-IRS staring mode targets in the Magellanic Clouds
Paul M. E. Ruffle, Paul M. Woods, F. Kemper
The SAGE-LMC, SAGE-SMC and HERITAGE surveys have mapped the Magellanic Clouds in the infrared using the Spitzer and Herschel Space Telescopes. Over 8.5 million point sources were d…
Galactic Edge Clouds I: Molecular Line Observations and Chemical Modelling of Edge Cloud 2
P. M. E. Ruffle, T. J. Millar, H. Roberts +5
Edge Cloud 2 (EC2) is a molecular cloud, about 35 pc in size, with one of the largest galactocentric distances known to exist in the Milky Way. We present observations of a peak CO…
Angular diameters, fluxes and extinction of compact planetary nebulae: further evidence for steeper extinction towards the Bulge
P. M. E. Ruffle, A. A. Zijlstra, J. R. Walsh +5
We present values for angular diameter, flux and extinction for 70 Galactic planetary nebulae observed using narrow band filters. Angular diameters are derived using constant emiss…
