CTIO spectral surveys of red giant stars
Abstract
An overview is given of the results of low-dispersion spectral surveys of distant red giants with attention given to special techniques for studying the objects. Studies are reported of the C/M ratio, the TiO band, as well as investigations that are purely photometric, and significant findings are given. C stars are known to have the same luminosity function regardless of the parent galaxy, and carbon stars manifest a heterogeneity that requires further study at higher dispersion.
