Spectroscopy of the M supergiant alpha Ori in the 1-2.5 µm region
(2005) ESO Workshop on High Resolution Infrared Spectroscopy in Astronomy p.419-422- Abstract
- The study of elemental abundances in cool stars via atomic lines in the optical region is made difficult by stellar molecular absorption. At infrared wavelengths this problem is diminished, but ground-based observations suffer from absorption by the earth's atmosphere. Fortunately, there are spectral windows through which we can observe. We have explored several such windows in the spectral region from 1-2.5 mu m, coinciding with the wavelength domain of the new VLT instrument CRIRES, for atomic lines suitable for the study of cool luminous stars, in particular alpha Ori (M21ab). We present preliminary results from this search along with our first results on abundances of iron and the weak s-process elements Sr, Y, Zr.
