    Radio continuum absorption observations at 34.5 MHz with a spatial resolution of 34 x 48 arcmin have been obtained for the giant H II region complex W 51 with the decameter-wave radio telescope at Gauribidanur, India (13 ...
  • Observations of the Interaction of Acoustic Waves and Small-scale Magnetic Fields in a Quiet Sun 
    Pradeep Chitta, L; Jain, R; Kariyappa, R; Jefferies, S. M (IOP Publishing, 2012-01-10)
    The effect of the magnetic field on photospheric intensity and velocity oscillations at the sites of small-scale magnetic fields (SMFs) in a quiet Sun near the solar disk center is studied. We use observations made by the ...

    Smith, C. M (Royal Astronomical Society, 1900-01)
  • Observations of the near and far ultraviolet background 
    Murthy, J (Springer, 2009-04)
    The diffuse ultraviolet radiation field is seen over the entire sky and is a tracer of both the hot (in the form of lines such as CIV and OVI) and cold component (in the form of interstellar dust or molecular hydrogen) of ...
  • Observations of the Rosette Nebula using the Decameter Wave Radio Telescope at Gauribidanur 
    Deshpande, A. A; Shevgaonkar, R. K; Sastry, Ch. V (D. Reidel Publishing Co., 1984-07)
    A map of Rosette Nebula in continuum absorption is made at 34.5 MHz using the Decameter Wave Radio Telescoe at Gauribidanur, India, with a resolution of 26×40, is presented. These observations are combined with the 2700 ...
  • Observations of the Solar Ca I 4227 Å Line 
    Bianda, M; Ramelli, R; Stenflo, J. O; Anusha, L. S; Nagendra, K. N; Sampoorna, M; Holzreuter, R; Frisch, H (Astronomical Society of the Pacific, 2011-04)
    Our aim is to understand some interesting polarization features observed in the solar Ca I 4277 Å line. Here we only discuss the observational aspects. Observations have also been made in other chromospheric lines within ...
  • Observations of the Structure of Type-IIIb Radio Bursts 
    Sastry, Ch. V; Subramanian, K. R; Krishnan, V (International Astronomical Union, 1980)
  • Observations of the supernova remnants HB 9 and IC 443 at 34.5 MHz 
    Dwarakanath, K. S; Shevgaonkar, R. K; Sastry, Ch. V (Indian Academy of Sciences, 1982-06)
    The results of observations of the two SNRs HB 9 and IC 443 are discussed. A map of HB 9 is presented whose main features are an elongation in the northerly direction and a strong region at the center of the map. The ...
  • Observations of the type IIp supernova 2001X during the plateau phase 
    Anupama, G. C; Sahu, D. K (Astronomical Society of India, 2002-09)

  • Observations of variables 
    Rosario, M. J; Muneer, S; Raveendran, A. V; Mekkaden, M. V (IBVS / Konkoly Observatory, 2010-12)
    UX Ari was observed on a total of 33 nights during December 2008-February 2010 in standard Johnson BV bands with the 34-cm tel escope of Vainu Bappu Observatory, Kavalur. All the measurements were made with respect to 62 ...
  • Observations of weak G-band stars 
    Kameswara Rao, N (Royal Astronomical Society, 1978-11)
    Scanner observations of the strengths of the G-band stars of CH at λ4300 and of the NH bands at λ3360 were obtained fro 10 weak G-band stars (wG stars) along with 2 normal field giants of spectral types G to K. the ...
  • Observations of X-Per in optical domain 
    Sharma, D. P; Nagaraja, B. V; Bhattacharyya, J. C; Mohin, S; Raveendran, A. V (Kluwer Academic Publishers, 1983-09)
    We have monitored the X-ray source X-Per (4U 0352+30) on 31 August, 1979 through aU filter for about 1.5 hr using 102-cm telescope of Kavalur observatory. During this period intensity of X-Per fluctuated for some time, on ...

    Jacob, W. S (Royal Astronomical Society, 1848-03)
  • Observations on spread-F at Kodaikanal 
    Sastri, J. H; Murthy, B. S (National Institute of Science Communication And Information Resources, 1975-06)
    A study of quarter-hourly ionograms of Kodaikanal (geomag. lat: O'6oN; dip: 3'5°N) showed several instances when the spread-F disappears and subsequently. reappears in two hrs or less during it night. Investigation of such ...
  • Observations on the Fine Structures in Solar Decametric Radio Emission 
    Gopalswamy, N; Thejappa, G; Sastry, Ch. V (Indian Institute of Astrophysics, Bangalore, 1984)
    The Solar decametric radio emission consists of a variety of fine structures. This reflects the complexity of the corona at this level. Two observations, viz. absorption bursts and short duration narrow band bursts are ...
