47 Tucanae: The Membership of Two RR Lyrae Variables
Abstract
Harvard variables 810, 814 are shown to be the first known RR Lyr variables belonging to the globular cluster 47 Tuc. Their periods are long for their Bailey types. Their radial velocities do not differ significantly from that of 47 Tuc. Their spectra show only a moderate degree of metal weakness.
