[80.07] Double-Mode RR LYRAE (RRd) Variables and a Blended RR LYRAE Pair in the Globular Cluster M3

T. M. Corwin (UNC Charlotte), B. W. Carney (UNC Chapel Hill)

Light curves are presented for the M3 variables V4, V68, V79, V87, V99, and V166, based on 183 CCD B images. The data were taken in 1992 and 1993 on the Kitt Peak 0.9-m telescope. V68 and V87 have long been known as double-mode pulsators, V79 has been recently identified as a double-mode pulsator (Clement et al. 1997), and V99 and V166 are identified here as double-mode pulsators. V4 has been previously identified as a blended RR Lyrae pair. The light curve of V4 is reproduced here by the sum of two RRab light curves of slightly different periods and different amplitudes.
