CHARACTERIZING the POPULATION of BRIGHT INFRARED SOURCES in the SMALL MAGELLANIC CLOUD
Kraemer, Kathleen E; Sloan, G C; Wood, Peter R; Jones, Olivia C.; Egan, Michael P.
We have used the Infrared Spectrograph (IRS) on the Spitzer Space Telescope to observe stars in the Small Magellanic Cloud (SMC) selected from the Point Source Catalog of the Midcourse Space Experiment (MSX). We concentrate on the dust properties of the oxygen-rich evolved stars. The dust composition has smaller contributions from alumina compared to the Galaxy. This difference may arise from the lower metallicity in the SMC, but it could be a selection effect, as the SMC sample includes more...[Show more]
