A Post-AGB star in the small magellanic cloud observed with the Spitzer Infrared spectrograph
We have observed an evolved star with a rare combination of spectral features, MSX SMC 029, in the Small Magellanic Cloud (SMC) using the low-resolution modules of the Infrared Spectrograph on the Spitzer Space Telescope. A cool dust continuum dominates the spectrum of MSX SMC 029. The spectrum also shows both emission from polycyclic aromatic hydrocarbons (PAHs) and absorption at 13.7 μm from C2H2, a juxtaposition seen in only two other sources, AFGL 2688 and IRAS 13416-6243, both...[Show more]
