Molecules and dust production in the Magellanic Clouds
Molecules and dust production in the Magellanic Clouds
We present ESO/VLT spectra in the 2.9-4.1 μm range for a large sample of infrared stars in the Small Magellanic Cloud (SMC), mainly carbon stars, massive oxygen-rich Asymptotic Giant Branch (AGB) stars, and red supergiants. Strong emission from Polycyclic Aromatic Hyrdrocarbons (PAHs) is detected in the spectrum of the post-AGB …
