    Evershed, John (Taylor and Francis, 1909)
  • Radial movement in Sun-spots 
    Evershed, John (The Royal Society, 1909-03)
  • Radial movement in Sun-spots (Second Paper) 
    Evershed, John (The Royal Society, 1910-01)
  • Radial movement in Sunspots 
    Evershed, John (Indian Institute of Astrophysics, Bangalore, 1909-02-03)
  • Radial velocities of seven Sersic galaxies 
    Prabhu, T. P (Indian Institute of Astrophysics, 1978)
    The radial velocities of 7 Sersic galaxies are reported. Three out of these (NGC 2903, 2997 and 5236) have published radial velocities prior to this work while the radial velocities of four remaining galaxies (NGC 922, ...
  • Radiation and structure of the solar atmosphere 
    Bappu, M. K. V (D. Reidel Publishing, 1979)
  • Radiation pressure in resonance lines 
    Peraiah, A (Indian Institute of Astrophysics, 1979-11)
    The effects of large scales gas motions on the radiation pressure in a resonance lines are investigated. We have assumed a medium with pure scattering together with emission in the continuum. A linear velocity law is ...
  • Radio Emission From The Quiet Sun and Active Regions at Decametric Wavelengths 
    Sastry, Ch. V (Indian Institute of Astrophysics, Bangalore, 1986)
    The Continuum emission from the Quiet Sun and active regions is the radiation from the solar atmosphere when there is no transient burst activity. At decametric wavelengths this radiation originates in the outer corona. A ...
  • Radio emission from the Solar Corona due to shock waves 
    Thejappa, G (Indian Institute of Astrophysics, Bangalore, 1988)
    The slowly drifting solar type II radio bursts are believed to be due to the flare associated shock waves propagating radially outward in the corona. The main observational characteristics of these bursts show that the ...
  • Radio Observations of Compact Sources in the Outer Solar Corona 
    Ramesh, R; Subramanian, K. R; Sastry, Ch. V (Indian Institute of Astrophysics, Bangalore, 1997)
    We have observed radio emission from the solar corona at a frequency of 77 MHz during the total solar eclipse on October 24, 1995 from our observatory at Gauribidanur. Sources of angular sizes less than or equal to 1.5' ...
  • Radio spectrograph observations of the recent soalr eclipse on October 24, 1995 
    Shanmugaraju, A; Umapathy, S (Indian Institute of Astrophysics, Banglaore, 1997)
    A solar radio spectrograph has been developed to observe the transient solar radio emissions in the band of 30 MHz at our School of Physics. A non trackable log periodic antenna having beam of 60 degree in E-W and 90 degree ...
  • Radium and the chromosphere 
    Evershed, John (Taylor and Francis, 1912-10)
  • Raman and Astronomy 
    Bappu, M. K. V (Indian Academy of Sciences, 1971-05)
  • 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 ...
  • Recent work at Arcetri 
    Evershed, M. A; Evershed, John (Taylor and Francis, 1932-09)
  • Recollections of seventy years of scientific work 
    Evershed, John (Elsevier, 1955)
    This article records some of the researches in solar physics undertaken during my life. These have included the following: prominence observations covering sixteen years; spectroheliograph work with a direct vision prism; ...
  • Reconstruction of Solar Features from an Image of Partially Eclipsed Sun 
    Krishnakumar, V; Venkatakrishnan, P (Indian Institute of Astrophysics, Bangalore, 1997)
    The photoheliograms obtained at Kodaikanal during the partial eclipse of the Sun on October 24, 1995 were digitised on a PDS microdensitometer. The lunar limb was used as a standard source for the digital reconstruction ...
  • Record of extended corona using colour video 
    Saxena, A. K; Samson, J. P. A; Lancelot, J. P (Indian Institute of Astrophysics, Bangalore, 1997)
    The entire event of the total solar eclipse of October 24 1995 was vediographed at our Kalpi camp. We have used SONY handy cam Video 8 Model No. CCD FX 280E PAL attached with 12x variable zoom lens. Partial eclipse was ...
  • The red shift of the D lines of sodium in the Sun 
    Evershed, John (Royal Astronomical Society, 1938-01)
  • The red shift of the iron lines at the edge of the Sun 
    Evershed, John (Royal Astronomical Society, 1936-01)
