K; Kameswara Rao, N; Sreedhar, Yuvraj Harsha; Sreekumar, P (IOP Publishing, 2017-09)
    The Ultra-Violet Imaging Telescope (UVIT) is one of the payloads in ASTROSAT, the first Indian Space Observatory. The UVIT instrument has two 375 mm telescopes: one for the far-ultraviolet (FUV) channel (1300–1800 Å), ...
  • Peculiarities in the Horizontal Branch Stars of Globular Cluster NGC 1851: Discovery of a Blue Straggler Companion to an EHB Star 
    Singh, G; Sahu, S; Subramaniam, A; Yadav, R. K. S (IOP Publishing, 2020-12-10)
    We present a study of far-UV (FUV) bright horizontal branch (HB) stars to understand the peculiarities seen in the HB sequence of the globular cluster NGC 1851, using ground- and space-based multiwavelength data. Optical ...
  • UVIT-HST-Gaia-VISTA study of Kron 3 in the small magellanic cloud: a cluster with an extended red clump in ultraviolet 
    Nayak, P. K; Subramaniam, A; Subramanian, S; Sahu, S; Mondal, C; Cioni, Maria-Rosa L; Bell, Cameron P. M; Bandyopadhyay, A; Chung, Chul (Oxford University Press on behalf of the Royal Astronomical Society, 2021-06)
    We have demonstrated the advantage of combining multiwavelength observations, from the ultraviolet (UV) to near-infrared, to study Kron 3, a massive star cluster in the Small Magellanic Cloud. We have estimated the radius ...
