  • Narlikar, J. V; Padmanabhan, T (Astronomical Society of India, 1983-12)
    The standard big bang models of classical cosmology are known to possess three defects. The oldest known defect is the spacetime singularity whose existence seems inevitable within the classical framework. The second defect ...
  • Khare, Pushpa (Astronomical Society of India, 1995)
    Quasar absorption lines are an important tool to probe the universe at high redshifts, as they enable us to observe galaxies and intergalactic clouds at large distances, which are virtually inaccessible otherwise. This ...
  • Subramanian, K. R; Ebenezer, E (Astronomical Society of India, 2002-09)
    Spectral observations of the Sun in the frequency range of 54 to 78 MHz in the November 24, 2000 solar flare showed quasi - periodic pulsations with periods in the range of 11 - 19 seconds. YOHKOH images of this flare ...
  • Lokanadham, B; Kiron, Y. R; Muneer, S (Astronomical Society of India, 1998-12)
  • Thakur, R. K (Astronomical Society of India, 1997)
    This paper has been written in a highly personal vein. It’s a resume of the very modest effort made by the author and his students in understanding some aspects of extragalactic astronomy and astrophysics during the former’s ...
  • A query 
    Madhava Rau, R (Astronomical Society of India, 1911-04)
  • Ravindra, B (Astronomical Society of India, 2003)
    The 3-D structure of quiet Sun chromospheric network magnetic field is studied by comparing the observed and computed chromospheric magnetograms. The comparison shows that the best correlation occurs at 1800 km above the ...
  • Sarma, M. B. K (Astronomical Society of India, 1975-09)
  • Peraiah, A (Astronomical Society of India, 1990)
    Various factors influencing the formation of spectral lines are described, emphasizing the physics of stellar atmospheres. Broadening mechanisms, photon or partial frequency redistribution, the role of chemical species are ...
  • Singal, A. K (Astronomical Society of India, 2005-06)
    Some basic concepts in use for making astronomical observations at radio wavelengths are introduced. In particular the importance of phase information for imaging in radio astronomy is highlighted. Using simple examples ...
  • Swarup, G (Astronomical Society of India, 1974-03)
  • Vats, H. O; Deshpande, M. R; Mehta, M; Shah, C. R; Shah, K. J (Astronomical Society of India, 1999)
    The time series of solar radio emission at 2.8 GHz is analysed using correlation methods. The analysis showed that this type of time series can be used to infer the rotation period of the source (in this case solar corona). ...
  • Thomas, R. M. C; Gangadhara, R. T (Astronomical Society of India, 2003)
    We present a relativistic model of pulsar radio emission by plasma accelerated along the rotating magnetic field lines projected on to a 2D plane perpendicular to the rotation axis. We have derived the expression for the ...
  • Venugopal, V. R (Astronomical Society of India, 1990)
    The radio emission from a few binary systems is discussed. RS CVn stars, the Algol-type systems CC Cassiopeae, AR Lacertae, Beta Persei, and the X-ray emitting radio stars Cygnus X-3 and Sco X-1 are considered. A brief ...
  • Apparao, K. M. V (Astronomical Society of India, 2000)
    The acceleration of high energy particles by a shock produced by the passage of the secondary object in the binary system, through the wind of the primary, is considered and is shown to be adequate to account for the ...
  • Kembhavi, A (Astronomical Society of India, 1998)
  • Yellaiah, G; Lodanadham, B (Astronomical Society of India, 1993)
    The radio observations of quadrantid meteor shower obtained during the period 1983-88 have been analyzed. Diurnal as well as yearly variations in the quadrantid meteor shower activity have been studied.
  • Kapoor, R. C; Shukre, C. S (Astronomical Society of India, 2002-09)
    By attributing the often seen longitude offsets between the core and conal component centres of pulsar radio pulses to different emission altitudes, we present a new method for investigating these altitudes. OUf method ...
  • Pant, P; Bondal, K. R (Astronomical Society of India, 1984-09)
    We report here the H-alpha observations of a large and complicated flare of optical class 2B which occured on 1982 April 14. The flare showed significant activity for several minutes prior to its impulsive phas, as evidenced ...
  • Gopal-Krishna (Astronomical Society of India, 1978-12)
    Some recently discovered properties of the radio source 4C - 05.93 are summarised. Their relevance to the observed absorption-line spectrum of the QSO PHL 5200, which is located onl 1 arcmin away from the radio source, is ...
