  • Lifetimes and sizes of supergranular cells 
    Raju, K. P; Srikanth, R; Singh, J (Astronomical Society of India, 1999)
    Supergranulation is the surface manifestation of large scale solar convection. Since there is a strong correspondence between supergranulation pattern and Ca K chromospheric network, lifetimes and sizes may be obtained ...
  • Morphology of Ca II K bright points and their link to G band bright points 
    Krishnakumar, V; Venkatakrishnan, P; Srikanth, R (Astronomical Society of India, 2000)
    We present the results of a preliminary analysis of a time series of a sequence of Ca II K bright points and G band bright points observed co-spatially and co-temporally. Inspection of these images shows that the larger ...
  • Narrow Band Photometry in Emission Lines during the Total Solar Eclipse of October 24, 1995 
    Singh, J; Cowsik, R; Venkatakrishnan, P; Srinivasan, R; Chinnappan, V; Raju, K. P; Srikanth, R (Indian Institute of Astrophysics, Bangalore, 1997)
    To investigate the spatial variation of tempereture and density within coronal strucures, narrow band photometry in three coronal emission lines was done during this eclipse. The emission lines 6374 (FeX), 7892 (Fe XI) and ...
  • On a generalized peaceful coexistence of special relativity and quantum mechanics 
    Srikanth, R (Elsevier, 2001-12)
    The result that quantum nonlocality is causal because it cannot be used to transfer classical information across spacelike intervals is extended to entangled n-partite systems (n2). We show that correlations between any m ...
  • On the Fractal Structure of Solar Supergranulation 
    Paniveni, U; Krishan, V; Singh, J; Srikanth, R (Springer, 2005-10)
    We employ fractal analysis to study the complexity of supergranulation structure using the Solar and Heliospheric Observatory (SOHO) dopplergrams. Our data consists of 200 visually selected supergranular cells, for which ...
  • Photospheric Flow Fields and Properties of Embedded Small-scale Magnetic Flux Concentrations 
    Rajaguru, S. P; Srikanth, R; Hasan, S. S (Astronomical Society of the Pacific, 2001)
    The association between the different scales of convection on the solar photosphere and the field strengths/flux contents of discrete magnetic flux elements are analysed using simultaneously recorded SOHO MDI high resolution ...
  • Physical Interpretation of the Poynting-Robertson Effect 
    Srikanth, R (Academic press, 1999-07)
    Although the prevalent mathematical description of the Poynting-Robertson effect is correct, its physical interpretation is sometimes problematic. By means of a two-parameter model, we revisit the effect in order to get a ...
  • Possible Evidence of Long-Term Oscillations in the Solar Atmosphere 
    Raju, K. P; Singh, J; Srikanth, R; Chou, Dean-Yi; CA, TON team (Springer, 2001-03)
    We have obtained the temporal correlation function, Q(t), from time sequences of Caii K filtergrams and Dopplergrams from Antarctica, Taiwan Oscillation Network (TON) and Solar and Heliospheric Observatory (SOHO). Q(t) ...
  • A quantum field theoretic description of the delayed choice experiment 
    Srikanth, R (Indian Academy of Sciences, 2001-11)
  • Relationship between horizontal flow velocity and cell lifetime for supergranulation from SOHO Dopplergrams 
    Paniveni, U; Krishan, V; Singh, J; Srikanth, R (Royal Astronomical Society, 2004-02-01)
    A study of 50 supergranular cells obtained from Solar and Heliospheric Observatory (SOHO) Dopplergrams was undertaken in order to investigate the relationship between the lifetime (T) and the horizontal flow velocity (vh) ...
  • Relationship between horizontal flow velocity and cell size for supergranulation using SOHO Dopplergrams 
    Krishan, V; Paniveni, U; Singh, J; Srikanth, R (Royal Astronomical Society, 2002-07)
    A study of 90 supergranular cells obtained from SOHO Dopplergrams was undertaken in order to investigate a possible relation between the sizes and peak horizontal velocities of the cells. For the sample obtained, the two ...
  • Solar Cycle Phase Dependence of Supergranular Fractal Dimension 
    Paniveni, U; Krishan, V; Singh, J; Srikanth, R (Indian Academy of Sciences, 2011-06)
    We study the complexity of supergranular cells using the intensity patterns obtained from the Kodaikanal Solar Observatory during the 23rd solar cycle. Our data consists of visually identified supergranular cells, from ...
  • Studies on the Solar Chromospheric Network 
    Srikanth, R (Indian Institute of Astrophysics, Bangalore, 1998-04)
  • Supergranulation and its Activity Dependence 
    Paniveni, U; Krishan, V; Singh, J; Srikanth, R (Cambridge University Press, 2011-08)
    We study the complexity of supergranular cells using the intensity patterns obtained at the Kodaikanal solar observatory during the solar maximum. Our data consists of visually identified supergranular cells, from which a ...
