  • Evolution of Optical Spectrum of SN 1987A 
    Kameswara Rao, N (Indian Institute of Astrophysics, 1988)
    The initial reaction to the spectroscopic behaviour of SN 1987A was that it is a very untypical SN II but after a year, it is said that it is not peculiar after all. Only it went through various stages very fast and that ...
  • Exploding the myths of creation 
    The Hindu (The Hindu, 1987-02-28)
  • Further spectroscopic observations of SN 1987A 
    Anupama, G. C; Prabhu, T. P; Ghosh, K. K; Ashoka, B. N; Giridhar, S (Elsevier, 1988)
    Spectroscopic observations of SN 1987a obtained during 1987 August 30 – September 8 from Vainu Bappu Observatory, Kavalur, are presented; the spectrum is compared and contrasted with the spectra recorded at earlier epochs. ...
  • New instrument tested at Kavalur observatory

  • Rotational Effects in SN 1987A 
    Ramadurai, S; Wiita, Paul J (Indian Institute of Astrophysics, 1988)
    The possible evolutionary effects of rotation on the observational characteristics of SN 1987A and it progenitor Sk -69 202, are explored. If rotation is important, decrease in post main sequence luminosity and increase ...
  • SN 1987A : Light Curves and Inferences 
    Prabhu, T. P (Indian Institute of Astrophysics, 1988)
    The UBVRI light curves of SN 1987a are described. The inferences one can draw from these data, such as the colour evolution, evolution of photospeheric radius and temperature, and bolometric light curve, are discussed. ...
  • SN1987A : Supernova Remnant Prospects 
    Velusamy, T (Indian Institute of Astrophysics, 1988)
  • Speckel Interferometry of SN 1987A and the "Mystery Spot" 
    Nityananda, Rajarama (Indian Institute of Astrophysics, 1988)
    Two groups have independently studied SN1987A by the technique of optical speckle interferometry in the visible region of wavelengths about a month after the explosion. Both detect a secondary source a factor of ten fainter ...
  • Supernova 1987A and its Implications to Neutrino Physics 
    Murthy, M. V. N (Indian Institute of Astrophysics, 1988)
    We review the reported neutrino events from the supernova SN 1987A and present a critical analysis of these events for their implications on the mechanism of stellar collapse as well as for neutrino physics.
  • Supernova 1987A in LMC : Infrared Observations 
    Bhatt, H. C (Indian Institute of Astrophysics, 1988)
    Results obtained from infrared observations of SN 1987A have been summarized. The supernova developed near-infrared excesses with a characteristic temperature ~1250 k beginning around March 15, 1987. Infrared speckle ...
  • Supernova observed from Kavalur Observatory
