  • Science with IUCAA telescope 
    Srianand, R; Gupta, R; Kembhavi, A; Ramaprakash, A. N; Tandon, S. N (Astronomical Society of India, 2002-09)
    We present a brief overview of the proposed astronomical observations using the first light instrument !FOSC for the WCAA 2 m telescope.
  • Small telescopes and robotics 
    Gupta, R (Astronomical Society of India, 1996)
    Over the past decade, Small Automated Telescopes have been developed at. various observatories. The operation of these telescopes and their related observations are carried out under the control of a computer and thus the ...
  • Small/automated telescopes and backend instrumentation for teaching purpose 
    Gupta, R (Astronomical Society of India, 2001)
    In the past decade, with the inception of IUCAA and other similar efforts from Universities and Institutes, several MSc teaching courses at Universities now offer Astronomy & Astrophysics as a special paper along with a ...
  • Spectroscopic and geometrical evolution of the ejecta of the classical nova ASASSN-18fv 
    Pavana, M; Raj, A; Bohlsen, T; Anupama, G. C; Gupta, R; Selvakumar, G (Oxford University Press on behalf of the Royal Astronomical Society, 2020-05)
    The optical spectroscopic observations of ASASSN-18fv observed from 2018 March 24 to 2019 January 26 are presented. The optical spectra are obtained from Mirranook, Vainu Bappu, and South African Astronomical observatories. ...

  • A three-dimensional automated classification scheme for the TAUVEX data pipeline 
    Bora, A; Gupta, R; Singh, H. P; Murthy, J; Mohan, Rekhesh; Duorah, K (Blackwell Publishing, 2008-02)
    In order to develop a pipeline for automated classification of stars to be observed by the Tel-Aviv University Ultra-Violet Experiment (TAUVEX) ultraviolet space telescope, we employ an artificial neural network (ANN) ...
  • Unveiling Vela – variability of interstellar lines in the direction of the Vela supernova remnant – III. Na D and Ca II K 
    Kameswara Rao, N; Lambert, D. L; Reddy, A. B. S; Gupta, R; Muneer, S; Singh, H. P (Oxford University Press on behalf of the Royal Astronomical Society, 2020-03)
    High-resolution optical spectra were obtained in 2017–2019 with The Southern African Large Telescope of 15 stars in the direction of the Vela supernova remnant. Interstellar Ca II H & K and Na I D lines are discussed in ...
  • Unveiling Vela: time variability of interstellar lines in the direction of the Vela supernova remnant – II. Na D and Ca II 
    Kameswara Rao, N; Lambert, D. L; Reddy, A. B. S; Gupta, R; Muneer, S; Singh, H. P (IOP Publishing, 2017-05)
    In a survey conducted between 2011 and 2012 of interstellar Na I D line profiles in the direction of the Vela supernova remnant (SNR), a few lines of sight showed dramatic changes in low-velocity absorption components with ...
