  • The Absolute Magnitudes of Wolf-Rayet Stars HD 151932 and HD 152270 
    Shylaja, B. S; Bappu, M. K. V (Indian Institute of Astrophysics, Bangalore, 1983)
    The absolute visual magnitudes of two Wolf-Rayet stars HD 151932 (WN 7) and HD 152270 (WC 7+08) have been determined from their energy distributions and monochromatic magnitudes least contaminated by emission lines taking ...
  • Atmospheric Extinction at Kavalur Observatory during 1980-85 
    Shylaja, B. S; Bhattacharyya, J. C (Indian Institute of Astrophysics, Bangalore, 1986)
    From a series of photoelectric scanner observations during 1980-85, the atmospheric extinction at Kavalur has been analysed. The variation of this appears to follow lamda/sup-4/ law. There is a general increase in the ...
  • Recent outburst of U ScorpII 
    Shylaja, B. S; Prabhu, T. P (Indian Institute of Astrophysics, 1979-11)
    A photoelectric scan of Hβ and a photographic spectrum between λλ 4500-7000 obtained during the 1979 outburst of the recurrent nova U Sco have been studied. The electron density and the mass of ionized hydrogen in the nova ...
  • The solar corona in the He II line 
    Shylaja, B. S (Indian Institute of Astrophysics, 1997)
    The corona of the sun was photographed with the filters centered at 4686Å, 4921 Å and 5812 Å, on 24th October 1995, during totality at Nim Ka Thana The PDS scans of these Images were presented The differences In the contours ...
  • Stone Inscriptions on Eclipses in Karnataka 
    Shylaja, B. S; Murthy, Chidananda. M (Indian Institute of Astrophysics, Bangalore, 1997)
    The solar and lunar eclipses have been documented on stone inscriptions in various parts of Karnataka, from the 9th century onwards. The records testify the knowledge of positional astronomy and also the cultural and ...
