  • Probes of the solar interior 
    Chitre, S. M; Antia, H. M (Astronomical Society of India, 1998)
    The interior of the sun is not directly accessible to observations. Nonetheless, it is possible to infer the physical conditions prevailing in the solar interior with the help of theory of stellar structure and the powerful ...
  • Redetermination of the Hubble Constant and the Deceleration Parameter 
    Chitre, S. M (Astronomical Society of India, 1975-03)
  • Schwarzschild orbital topography and high doppler blueshifts 
    Stoeger, W. R; Chitre, S. M; Narlikar, J. V; Kapoor, R. C (Nature Publishing Group, 1975-01)
  • Sizing up the universe with cosmic illusions 
    Chitre, S. M (Astronomical Society of India, 1994)
    The role of gravitational lenses as valuable tools for astrophysics and cosmology is highlighted. The importance of studying gravitational lens systems for inferring the nature and distribution of gravitating matter, both ...
  • Solar Convection and Oscillations 
    Chitre, S. M (Indian Institute of Astrophysics, Bangalore, 1986)
    A wide variety of gravity and acoustic wave motions have been detected at the surface of the Sun as Doppler shifts of spectral lines. These velocity field provide a valuable probe for studying the internal solar structure ...
  • Straight arcs in gravitational lens systems 
    Narasimha, D; Chitre, S. M (Astronomical Society of India, 1993)
    Faint straight arcs extending over ten to twenty arcseconds have been observed behind rich clusters of galaxies elongated by the lensing action of the foreground cluster. When a cluster of galaxies has its projected surface ...
  • Waves in the sunspot penumbra 
    Antia, H. M; Chitre, S. M; Gokhale, M. H (Springer, 1978-11)
    Sunspot theory is discussed with reference to the role played by the spot magnetic field in influencing the mode of energy transport. Consideration is given to the stability of a plane parallel polytropic fluid layer with ...
  • Winter School on High Energy Astrophysics 
    Narlikar, J. V; Chitre, S. M (Astronomical Society of India, 1976-06)
  • Zonal velocity bands and the solar activity cycle 
    Sivaraman, K. R; Antia, H. M; Chitre, S. M; Makarova, V. V (Springer Netherlands, 2008-09)
    We compare the zonal-flow pattern in subsurface layers of the Sun with the distribution of surface magnetic features such as sunspots and polar faculae. We demonstrate that, in the activity belt, the butterfly pattern of ...
