  • 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 ...
  • Sahoo, B. K; Md. Islam, R; Das, B. P; Chaudhuri, R. K; Mukherjee, D (The American Physical Society, 2006-12)
    Atomic properties involving the low-lying excited D3/2,5/22 states in alkaline-earth-metal ions are of current interest in many different applications ranging from tests of physics beyond the standard model to astrophysics. ...
  • Antokhina, E. A; Srinivasa Rao, M; Parthasarathy, M (Elsevier B.V, 2011-04)
    Hipparcos photometric data for the massive O-type binary UW CMa were analysed within the framework of the Roche model. Photometric solutions were obtained for five mass ratios in the q = M2/M1 = 0.5–1.5 range. The system ...

    We present the low-resolution spectroscopic and UBVRI broad-band photometric investigations of the Type IIb supernova (SN) 2011fu, discovered in UGC 01626. The photometric follow-up of this event was initiated a few days ...
  • Gangopadhyay, A; Misra, K; Pastorello, A; Sahu, D. K; Singh, M; Dastidar, R; Anapuma, G. C; Kumar, B; Pandey, S. B (Societe Royale des Sciences de Liege, 2018-04)
    Stripped-Envelope Supernovae constitute the sub-class of core-collapse supernovae that strip off their outer hydrogen envelope due to high stellar winds or due to interaction with a binary companion where mass transfer ...
  • Narayana, J. V; Viswanadham, P (Government Observatory, Madras, 1965-11)
  • Ivanov, V. P; Kjurkchieva, D. P; Srinivasa Rao, M (Astronomical Society of India, 2010-09)
    We propose a procedure for light-curve solutions of eclipsing binary stars in the Small Magellanic Cloud (SMC) for which photometric data have been obtained in the framework of the OGLE project. We also present a way of ...
  • Kulkarni, A. G; Abhyankar, K. D (Astronomical Society of India, 1977-12)
  • Chatterjee, S (Institute of Physics and IOP Publishing Limited, 2003-03)
    We study the scattering of light by a dielectric film with a periodic gradation of the refractive index along its thickness. The intensity of the scattered light is calculated in the scalar wave approximation, in which the ...
  • Venkata Suresh, Narra; Prasad, B. R (SPIE, 2021-07)
    To meet the proposed science goals of the Visible Emission Line Coronagraph on board the Aditya-L1 mission, the total scattered light should be less than 5 ppm (parts per million) of solar disk brightness over the field ...
  • Raveendran, A. V (D. Reidel Publishing Company, 1984-02)
    Photometry of the spectroscopic binary BD +25°2511 obtained during the 1981, 1982, and 1983 observing seasons shows that it is a variable with a period of about 3.5 days.
  • Fujii, T; Nakad, Y; Parthasarathy, M (Kluwer Academic Publishers, 2001-08)
    The transition from AGB to post-AGB stars was investigated using the H-band monitoring of these objects for four years. The Mira-type pulsations were found only in the restricted area in the IRAS two color diagram. The ...
  • Bappu, M. K. V (Taylor and Francis, 1959-06)
  • Gupta, S. K (Astronomical Society of India, 1979-09)
    The light curves of the delta Scuti star variable 38 Cnc, which is a member of the Praesepe cluster, have been analysed using the techniques of periodogram analysis and least square solutions. The star pulsates in the ...

  • Banyal, R. K; Prasad, B. R (American Institute of Physics, 2003-06-15)
    We present the experimental results on the measurement of temporal and steady-state light-induced absorption change in undoped and rhodium-doped barium titanate (Rh:BaTiO3) crystals at different wavelengths and intensities. ...
  • Abhyankar, K. D; Panchatsaram, T (Astronomical Society of India, 1982-12)
    An analysis of the minimum-time data of AK Her and ER Ori revelas possible sinudodal variations in their orbital periods. In the case of AK Her we suspect two additional components; one of mass 0.2 to 0.4 MSun with a period ...
