AGB stars in extragalactic systems
M. A. T. Groenewegen
I will be reviewing three methods to identify late-type giants in extragalactic systems, based on the main characteristics of AGB stars (they are infrared bright, variable, and hav…
Spitzer spectroscopy of carbon stars in the Small Magellanic Cloud
Eric Lagadec, Albert A. Zijlstra, G. C. Sloan +12
We present Spitzer Space telescope spectroscopic observations of 14 carbon-rich AGB stars in the Small Magellanic Cloud. SiC dust is seen in most of the carbon-rich stars but it is…
ISO Mid-Infrared Spectroscopy of Galactic Bulge AGB Stars
Joris A. D. L. Blommaert, Martin A. T. Groenewegen, Koryo Okumura +8
To study the nature of Bulge AGB stars and in particular their circumstellar dust, we have analysed mid-infrared spectra obtained with the ISOCAM CVF spectrometer in three Bulge fi…
Spitzer observations of acetylene bands in carbon-rich AGB stars in the Large Magellanic Cloud
M. Matsuura, P. R. Wood, G. C. Sloan +13
We investigate the molecular bands in carbon-rich AGB stars in the Large Magellanic Cloud (LMC), using the InfraRed Spectrograph (IRS) on board the Spitzer Space Telescope (SST) ov…
Near-Infrared Photometry of Carbon Stars
Patricia A. Whitelock, Michael W. Feast, Freddy Marang +1
Near-infrared, JHKL, photometry of 239 Galactic carbon-rich variable stars is presented and discussed. From these and published data the stars were classified as Mira or non-Mira v…
A Spitzer mid-infrared spectral survey of mass-losing carbon stars in the Large Magellanic Cloud
Albert A. Zijlstra, Mikako Matsuura, Peter R. Wood +13
We present a Spitzer Space Telescope spectroscopic survey of mass-losing carbon stars (and one oxygen-rich star) in the Large Magellanic Cloud. The spectra cover the wavelength ran…
