Anomalous RR Lyrae stars(?). III. CM Leonis
L. Di Fabrizio, G. Clementini, M. Marconi +8
Time series of B,V,I CCD photometry and radial velocity measurements from high resolution spectroscopy (R=30,000) covering the full pulsation cycle are presented for the field RR L…
Variable Stars in the Unusual, Metal-Rich Globular Cluster NGC 6388
Barton J. Pritzl, Horace A. Smith, Marcio Catelan +1
We have undertaken a search for variable stars in the metal-rich globular cluster NGC 6388 using time-series BV photometry. Twenty-eight new variables were found in this survey, in…
M75, a Globular Cluster with a Trimodal Horizontal Branch. I. Color-Magnitude Diagram
M. Catelan, J. Borissova, F. R. Ferraro +3
Deep UBVI photometry for a large field covering the distant globular cluster M75 (NGC 6864) is presented. We confirm a previous suggestion (Catelan et al. 1998a) that M75 possesses…
B,V Photometry of Variable Stars in the Northeast Arm of the Small Magellanic Cloud
Brian Sharpee, Michele Stark, Barton Pritzl +4
B and V photometry has been obtained for variable stars in the northeast arm of the Small Magellanic Cloud (SMC). Periods and lightcurves have been determined for 237 periodic vari…
