  • Spectroscopy of novae and supernovae 
    Prabhu, T. P (Astronomical Society of India, 1993)
    Many novae have been studied spectroscopically since 1975 and many supernovae since 1980 using the telescopes at Vainu Bappu Observatory (VBO). The program on novae has intensified since 1985, and that on supernovae has ...
  • Towards radial velocity measurements with iodine absorption cell on VBT Echelle Spectrograph 
    Sireesha, C (Indian Institute of Astrophysics, 2015-08)
    Essentially all information about astronomical objects outside the solar system reach us via light, i.e., the electromagnetic radiation. White light is composed of many wavelengths which are not resolved into their ...
  • X-ray spectrum of NGC 3783 - Detection of soft excess and an emission line 
    Ghosh, K. K; Soundararajaperumal, S; Kalai Selvi, M; Sivarani, T (EDP Sciences, 1992-02)
    Results of the X-ray (0.1-10 keV) spectral analysis of the Seyfert I galaxy, NGC 3783, which was observed with EXOSAT on three epochs between 1983 and 1985, are presented here. No low energy absorption, intrinsic to the ...
