  • Interior and exterior clues of solar activity 
    Turck-Chièze, S; Brun, A. S; Duez, V; García, R. A; Mathis, S; Piau, L; Salabert, D; Pallé, P. L; Jiménez-Reyes, S. J; Mathur, S; Simoniello, R; Robillot, J. M (Springer, 2010)
    Two research paths are described to obtain better understanding of the origin of global solar activity. First, observations with a multichannel resonant spectrometer may reveal the dynamics of the solar core, the tachocline, ...
  • Viscous damping of Alfven surface waves with steady flows 
    Rathinavelu, G. D; Sivaraman, M; Satya Narayanan, A (Springer, 2010)
    The dispersion relation of Alfvén Surface Waves propagating along the moving viscous plasma–vacuum interface has been derived and solved numerically. The plasma layer is below while the upper layer is assumed to be vacuum. ...
  • Revisit of the classic Wilson effect 
    Bagare, S. P (Springer, 2010)
    We have examined theWilson effect in 580 epochs of sunspots observed at the Kodaikanal Observatory. Only unipolar spots that are well isolated from opposite polarity spots or pores (49%) exhibit the classic Wilson effect. ...
  • Are polar faculae generated by a local dynamo? 
    Sivaraman, K. R; Antia, H. M; Chitre, S. M (Springer, 2010)
    Polar faculae (PF) are bright, small-scale structures measuring a few seconds of arc, populating the polar zones at latitudes >50°. They possess magnetic fields ranging from 150 to 1,700 Gauss and largely constitute the ...
  • Coronal magnetic field estimation using type-II radio bursts 
    Subramanian, K. R; Ebenezer, E; Raveesha, K. H (Springer, 2010)
    Coronal magnetic fields at two different heights were estimated using multiple type-II radio bursts observed on 23 January 2003. The strength of the magnetic field was estimated using 1–5 times the Newkirk density value. ...
  • MG II emission of Pop. 2 long-period Cepheids 
    Parthasarathy, M; Parsons, S. B (1984-12)
    The Population II Cepheid pulsational variables AL Vir (P = 10.3 days) and W Vir (P = 17.3 days) were observed with IUE at two phases each. Only low-dispersion mid-UV exposures were feasible, but were sufficient to show a ...
  • Spectroscopic study of a few Herbig Ae/Be stars in young open clusters 
    Mathew, B; Subramaniam, A; Bhavya, B (Astronomical Society of India, 2010-03)
    In this article we give an overview of the developments in the field of spectral classification and its continued importance in the fields of stellar and galactic evolution. The extension of MK system to cool stars as well ...
  • Nonlinear response studies and corrections for a liquid crystal spatial light modulator 
    Banyal, R. K; Prasad, B. R (Indian Academy of Sciences, 2010-06)
    The nonlinear response of light transmission characteristics of a liquid crystal (LC) spatial light modulator (SLM) is studied. The results show that the device exhibits a wide range of variations with different ...
  • Report of the Indian expedition to Ceylon to observe the total solar eclipse of 20 June 1955 
    Das, A. K (The India Meteorological Department, 1956-10)
  • The Milky Way Tomography with SDSS. III. Stellar Kinematics 
    Bond, N. A; Ivezić, Z; Sesar, B; Jurić, M; Munn, J. A; Kowalski, A; Loebman, S; Roškar, R; Beers, T. C; Dalcanton, J; Rockosi, C. M; Yanny, B; Newberg, H. J; Prieto, C. A; Wilhelm, R; Lee, Y. S; Sivarani, T; Majewski, S. R; Norris, J. E; Bailer-Jones, C. A. L; Fiorentin, P. R; Schlegel, D; Uomoto, A; Lupton, R. H; Knapp, G. R; Gunn, J. E; Covey, K. R; Smith, J. A; Miknaitis, G; Doi, M; Tanaka, M; Fukugita, M; Kent, S; Finkbeiner, D; Quinn, T. R; Hawley, S; Anderson, S; Kiuchi, F; Chen, A; Bushong, J; Sohi, H; Haggard, D; Kimball, A; McGurk, R; Barentine, J; Brewington, H; Harvanek, M; Kleinman, S; Krzesinski, J; Long, D; Nitta, A; Snedden, S; Lee, B; Pier, J. R; Harris, H; Brinkmann, J; Schneider, D. P (IOP Publishing, 2010-06-10)
    We study Milky Way kinematics using a sample of 18.8 million main-sequence stars with r < 20 and proper-motion measurements derived from Sloan Digital Sky Survey (SDSS) and POSS astrometry, including ~170,000 stars with ...

  • Solar cycle and seasonal variations in the equatorial ionospheric F-region 
    Ganesh, K. S (Pergamon Press Ltd, 1965)
    Representative (N -- h) profiles have been obtained from Kodaikanal ionograms covering a period of about one solar cycle, for the study of the effect of solar activity on the ionic densities at different levels in the ...

    Subrahmanyan, R. V (Pergamon Press Ltd, 1964)
    Solar flare effects associated with the relativistic flares (flares during which very fast solar particles, mainly protons, of cosmic-ray energies were observed at ground level) are compared with those of non-relativistic ...
