  • Reconstruction of the past total solar irradiance on short timescales 
    Jain, K; Hasan, S. S (American Geophysical Union, 2004)
    The aim of this investigation is to present a new analysis of short-term variations in total solar irradiance by developing regression models and to extend these to epochs when irradiance measurements were not available. ...
  • Report of the Symposium on Relativistic Astrophysics 
    Apparao, M. V. K; Daniel, R. R (Astronomical Society of India, 1977-03)
  • Rotation curves of galaxies: missing mass or missing physics 
    Krishan, V (Indian Academy of Science, 1997-07)
    The rotation curves of galaxies are modelled using very special properties of an hydrodynamically turbulent fluid possessing helicity fluctuations. The development of correlations among these fluctuations leads to the ...

    One of the major science goals of the Visible Emission Line Coronagraph (VELC) payload aboard the Aditya-L1 mission is to map the coronal magnetic field topology and quantitative estimation of longitudinal magnetic field ...
  • Starward launch: Aditya-L1 to carry payload to study Sun’s corona 
    The New Indian Express (The New Indian Express, 2023-09-02)
  • Strong gravity, black holes, and hadrons 
    Sivaram, C; Sinha, K. P (American Physical Society, 1977-09)
    Certain similarities and analogies between the properties of black holes and elementary particles are considered in the framework of the strong gravitational field. Properties examined include measurable parameters (mass, ...
  • Studies on the E2-transition in CoXVII 
    Ray, H (EDP Sciences, 2002-09)
    The spectrum of the solar corona, plasma spectra, astrophysical objects and fusion devices exhibit forbidden lines in alkali-like ions. Ions belonging to the iron group are particularly important in this respect. More ...
  • Study of Atomic and Molecular Many Body Processes in Astrophysics 
    Majumder, Sanjoy (Indian Institute of Astrophysics, Bangalore, 2001-03)
  • Supernovae study: Context of the 4-m International Liquid Mirror Telescope 
    Kumar, B; Pandey, S. B; Pandey, Kanhaiya L; Anapuma, G. C; Surdej, J (Societe Royale des Sciences de Liege, 2018-04)
    The upcoming 4-m International Liquid Mirror Telescope (ILMT) facility will perform deep imaging (in single scan g 0 ∼22 mag) of a narrow strip of sky each clear night in the Time Delayed Integration mode. A cadence of ...
  • Symposium on "Some Aspects of Astrophysics" 
    Varma, R. K (Astronomical Society of India, 1974-12)
