CCD time-series photometry of the globular cluster NGC 5053 RR Lyrae, blue stragglers and SX Phoenicis stars revisited. (2010)

Keywords : stars horizontal branch - stars: individual: RR Lyrae - globular clusters: individual: NGC 5053

Abstract:We report the results of CCD V, r and I time-series photometry of the globular cluster NGC 5053. New times of maximum light are given for the eight known RR Lyrae stars in the field of our images, and their periods are revised. Their V light curves were Fourier decomposed to estimate their physical parameters. ...(more)

The observations employed in the present work were performed using the Johnson V, R and I filters and obtained with the 2.0-m telescope of the Indian Astronomical Observatory (IAO), Hanle, India, located at 4500m above sea level, during several runs between 2006 April and 2009 January. The cluster was observed during a total of 10 nights, and 151 images were gathered in the Johnson V, 139 in R and 13 in I.
