Optical and Infrared Observations of Stellar Mass Loss in Globular Cluster Red Giants

Abstract

We are examining mass loss from globular clusters giant stars, focussing on metallicity dependance. We present three sets of observations: TIMMI-2 mid-IR spectra of 47 Tuc, UVES high-resolution optical spectra of several clusters, and an infrared atlas of omega Cen using the Spitzer Space Telescope.
