RV Tau Variables in Globular Clusters: Clues on Their Nature?
Abstract
We report on the detailed elemental abundances of RV Tau variables that reside in globular clusters, and how they compare with those of RV Tau variables in the field. Surprisingly, they seem to show definite differences, and at this stage, it is not clear why this is so.
