  • Intensity Fluctuations in the H-alpha line caused by Chromospheric mottling 
    Bappu, M. K. V (IETE, 1964)
    Spectra of the H-alpha line obtained with high dispersion and high spatial resolution are used to study some of the characteristics of chromospheric mottling on the solar disk. The fluctuations in intensity, indicated by ...

J; Jiang, X (Baltic Astronomy, 1998-03)
    A summary of the results on PQ Gem based on WET observations conducted in February 1996 is presented. The 13.9 min spin period of the white dwarf in the system and the orbital side-band at 14.5 min have been detected ...
  • Interplanetary Scintillation 
    Alurkar, S. K (Indian Institute of Astrophysics, Bangalore, 1988)
    In this tutorial talk, the ground-based, inexpensive method of interplanetary scintillation (IPS) is described, starting with a general background of scattering of e.m. radiation in turbulent media. This is followed by the ...
  • Introduction to Supernova Phenomena 
    Krishan, V (Indian Institute of Astrophysics, 1988)
  • An investigation of the displacement of unsymmetrical lines under different conditions of the electric agc 
    Royds, T (Indian Institute of Astrophysics, Bangalore, 1914-08-06)
  • Ionospheric electron content and equivalent slab thickness in the equatorial region 
    Das Gupta, A; Basu, S; Bhar, J. N; Bhattacharyya, J. C (American Geophysical Union, 1975-02)
    The ionospheric total electron content and equivalent slab thickness in the equatorial region around 75° E have been studied. It is found that the slab thickness exhibits a strong latitudinal dependence with a maximum at ...
  • Ionospheric Indication of Short-time Solar Activity Variations 
    Bhattacharyya, J. C; Sunder, R. S (PID [Publications and Information Directorate], 1970)
    A series of Lyot filtergrams have been photometrically analysed and the variations in the plage intensity determined on a number of days. From simultaneous ionosonde records, correlation has been sought between the electron ...
  • Is Venus cloud covered? 
    Evershed, John (Royal Astronomical Society, 1919)
  • Isodensitometry of Omega Centauri and 47 Tucanae 
    Scaria, K. K (Indian Institute of Astrophysics, Bangalore, 1980)
    We present details of procedure on equidensitometry of globular clusters using the Sabattier technique in photography. Equidensitometry of Omega Centauri and 47 Tuc shows that both clusters become more elliptical beyond r ...

  • John Evershed: The Instrument Builder 
    Bagare, S. P; Vagiswari, A; Birdie, C (Indian Institute of Astrophysics, 2008-12)
  • K emission line widths in the sun and the stars 
    Bappu, M. K. V; Sivaraman, K. R (Royal Astronomical Society, 1977-02)
    K-emission line widths measured with a micrometer on integrated spectra of the sun have a mean value of 38.2 km/s. A definition is proposed whereby the width is a measure in km/s at the inverse-e value of the difference ...
