Water vapor in the outer atmospheres of red giants probed by high-resolution, mid-infrared observations
Abstract
Here, we report on our detection of water vapor in the mid-infrared (11-12 microns) spectrum of the K1.5 giant. Arcturus (α Boo) obtained with the high-resolution, infrared spectrograph TEXES. The detection is presented in detail in Ryde et al. 2002 ApJ. We are successful in modeling several resolved, rotational lines of water vapor and vibration-rotational (1.5-microns) and rotational lines of OH with a modified MARCS photosphere.
