  • Ultra-low dispersion spectroscopy of stars and galaxies 
    Bappu, M. K. V; Parthasarathy, M (Indian Institute of Astrophysics, Bangalore, 1977)
    Application of ultra-low dispersion spectroscopy (10.000 Å mm-1) is described to study the nuclei of elliptical galaxies, the quassi - stellar objects and for the discovery of faint OB stars, reddened stars and red stars. ...
  • SN1987A : Supernova Remnant Prospects 
    Velusamy, T (Indian Institute of Astrophysics, 1988)
  • Supernova Shock 
    Thejappa, G (Indian Institute of Astrophysics, 1988)
    A Violent shock is formed at the site of the collision of inner and outer cores of a collasping star and the supernova explosion is born. Here we briefly review the evolution of the shock from its birth until its death.
  • Gravitational Waves from Collapsing Stars 
    Sivaram, C (Indian Institute of Astrophysics, 1988)
  • Neutrinos from SN 1987A 
    Sivaram, C (Indian Institute of Astrophysics, 1988)
  • Observational Results from SN1987A and their Implications on Theoretical Modelling of Supernovae 
    Ray, Alak (Indian Institute of Astrophysics, 1988)
    In the approximately one year since the explosion of the Supernova 1987A in the Large Magellanic Cloud, a large amount of work, both observational as well as theoretical, has been undertaken. Stan Woosley, a prolific worker ...
  • 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 ...
  • ASPEN Workshop on Supernova Physics 
    Ramadurai, S (Indian Institute of Astrophysics, 1988)
  • 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. ...
  • 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.
  • Future X-Ray and Gamma Ray Observations of SN 1987A 
    Marar, T. M. K (Indian Institute of Astrophysics, 1988)
    A brief outline of the prospects for carrying out X-ray and gamma ray observations of SN 1987A in the near future is presented in this paper.
  • Introduction to Supernova Phenomena 
    Krishan, V (Indian Institute of Astrophysics, 1988)
  • 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 ...
  • Polarimetry of Supernova SN 1987A - A Dust Shell Model 
    Joshi, U. C; Sen, A. K; Deshpande, M. R; Jain, Rekha (Indian Institute of Astrophysics, 1988)
    Polarimetric measurements of SN1987A in BVR bands were made on March 6 and 7. These observations along with the polarimetric data reported by various other authors within first 30 days of explosion have been discussed. ...
  • Equation of State of Supernova Matter 
    Datta, Bhaskar (Indian Institute of Astrophysics, 1988)
  • 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 ...
