  • Detection of a white dwarf companion to a blue straggler star in the outskirts of globular cluster NGC 5466 with the ultraviolet imaging telescope (UVIT) 
    Snehalata Sahu; Subramaniam, A; Simunovic, Mirko; Postma, J; Cote, Patrick; Kameswara Rao, N; Geller, Aaron M; Leigh, Nathan; Shara, Michael; Puzia, Thomas H; Stetson, Peter B (IOP Publishing, 2019-05-01)
    We report the discovery of a hot white dwarf (WD) companion to a blue straggler star (BSS) in the globular cluster (GC) NGC 5466, based on observations from the Ultra-Violet Imaging Telescope (UVIT) on board AstroSat. ...
  • Detection of White Dwarf companions to Blue Straggler Stars from UVIT observations of M67 
    Sindhu, N; Subramaniam, A; Geller, A. M; Jadhav, Vikrant; Knigge, Christian; Simunovic, Mirko; Leigh, Nathan; Shara, Michael; Puzia, T. H (Cambridge University Press, 2019-05)
    We investigate the old open cluster M67 using ultraviolet photometric data of Ultra-Violet Imaging Telescope in multi-filter far-UV bands. M67, well known for the presence of several blue straggler stars (BSS), has been ...
  • Globular Cluster UVIT Legacy Survey (GlobULeS) – I. FUV–optical colour–magnitude diagrams for eight globular clusters 
    Sahu, Snehalata; Subramaniam, A; Singh, Gaurav; Yadav, Ramakant; Valcarce, Aldo R; Choudhury, Samyaday; Sharmila Rani; Deepthi, S. Prabhu; Chung, Chul; Cote, Patrick; Leigh, Nathan; Geller, Aaron M; Chatterjee, Sourav; Kameswara Rao, N; Bandyopadhyay, Avrajit; Shara, Michael; Dalessandro, Emanuele; Pandey, G; Postma, Joesph E; Hutchings, John; Simunovic, Mirko; Stetson, Peter B; Sivarani, T; Puzia, Thomas; Sohn, Young-Jong (Oxford University Press on behalf of the Royal Astronomical Society, 2022-07)
    We present the first results of eight globular clusters (GCs) from the AstroSat/UVIT Legacy Survey programme GlobULeS based on the observations carried out in two far-ultraviolet (FUV) filters (F148W and F169M). The ...
  • Globular Cluster UVIT Legacy Survey (GlobULeS). III. Omega Centauri in Far-ultraviolet 
    Deepthi, S. Prabhu; Subramaniam, A; Sahu, Snehalata; Chung, Chul; Leigh, Nathan W. C; Dalessandro, Emanuele; Chatterjee, Sourav; Kameswara Rao, N; Shara, Michael; Cote, Patrick; Choudhury, Samyaday; Pandey, G; Valcarce, Aldo A. R; Singh, G; Postma, Joesph E; Sharmila Rani; Bandyopadhyay, Avrajit; Geller, Aaron M; Hutchings, John; Puzia, Thomas; Simunovic, Mirko; Sohn, Young-Jong; Sivarani, T; Yadav, Ramakant Singh (American Astronomical Society, 2022-11-10)
    We present the first comprehensive study of the most massive globular cluster, Omega Centauri, in the farultraviolet (FUV), extending from the center to ∼28% of the tidal radius using the Ultraviolet Imaging Telescope on ...
  • UVIT open cluster study. I. detection of a white dwarf companion to a blue straggler in M67: evidence of formation through mass transfer 
    Sindhu, N; Subramaniam, A; Jadhav, V. V; Chatterjee, Sourav; Geller, Aaron M; Knigge, Christian; Leigh, Nathan; Puzia, Thomas H; Shara, Michael; Simunovic, Mirko (IOP Publishing, 2019-09-01)
    The old open cluster M67, populated with blue straggler stars (BSSs), is a well-known test bed to study the BSS formation pathways. Here, we report the first direct detection of a white dwarf (WD) companion to a BSS in ...
