CCD time-series photometry of the globular cluster NGC 5053: RR Lyrae, Blue Stragglers and SX Phoenicis stars revisited

Arellano Ferro, A; Giridhar, S; Bramich, D. M (Blackwell Publishing, 2010-02)

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 ...
Stellar populations in the magellanic clouds

Subramanian, S; Subramaniam, A (Astronomical Society of India, 2013)

The structural parameters of the Large Magellanic Cloud and the Small Magellanic Cloud are derived from the study of di erent stellar populations, such as, Cepheids (age 100 Myr), Red Clump stars (age 2-9 Gyr) and RR ...
UV observations of globular clusters and nearby galaxies

Subramaniam, A (Astronomical Society of India, 2007-06)

We propose to identify the hot stellar population of the galactic globular clusters (GCs) using the TAUVEX. These stars can be easily identified in the core of the GCs where the crowding due to the main-sequence stars get ...
