Time Series CCD Photometry of the Globular Cluster M 53
Published online by Cambridge University Press: 12 April 2016
Abstract
Through time-series CCD photometry of the globular cluster M 53, we have discovered eight new SX Phoenicis type stars. All the new SX Phoenicis stars are located in the blue straggler star region in the color-magnitude diagram of M 53. In addition, we have obtained light curves for 45 known RR Lyrae stars.
