  • Emission line diagnostics for a coronal condensation 
    Raju, P. K (Astronomical Society of Indian, 1989-09)
    Theoretical line emission rates for the coronal ions Fe X, Fe XI, FE XIII, Fe XIV, Ca XII, Ca XIII, and Ca XV, have been used to obtain various line intensity ratios as a function of electron density and electron temperature. ...
  • Emission lines from nitrogen-like ions and their diagnostic use 
    Raju, P. K; Dwivedi, B. N (Kluwer Academic Publishers, 1990-11)
    Line emissions from nitrogen-like ions NeIV, MgVI, and AlVII have been studied as a diagnostic probe for the emitting regions of astrophysical plasma. Line intensities from these ions have been calculated and compared, in ...
  • Importance of atomic and molecular research for astronomical interpretation 
    Raju, P. K (World Scientific, 1987)
  • Line emission from the quiet sun and the coronal hole regions 
    Dwivedi, B. N; Raju, P. K (Astronomical Society of India, 1985-12)
    Using Kopp & Orrall (1976) model for the electron density and temperature for the quiet sun and the coronal hole regions, we have computed emission line intensities from Mg VIII, Si X (boron-like); Mg VII, Si IX (Carbon-like) ...
  • On the line ratio diagnostics for NeV, MgV, SiVII and Mg VII solar ions 
    Dwivedi, B. N; Mohan, Anita; Raju, P. K (Elsevier, 1997)
    We present NeV/MgV and MgVII/SiVII theoretical line intensity ratios as a function of electron density and temperature for physical conditions within the solar chromosphere-corona transition region. The electron pressure ...
  • Optical emission from solar corona 
    Raju, P. K (Indian Institute of Astrophysics, Bangalore, 1988)
    In this article the methods to probe the solar corona are briefly described. The discussion is confined to continuum and the "optical" wavelength region ~ 0.3 mum to 1.1 mum.
