    Ebenezer, E; Subramanian, K. R; Ramesh, R; Sundararajan, M. S; Kathiravan, C (Astronomical Society of India, 2007-06)
    We describe the Gauribidanur radio array solar spectrograph (GRASS) and its various systems. The system consists of an array of 8 log periodic dipoles,a spectrum analyzer and a data acquisition system. The spectrograph ...
  • UV observations of globular clusters and nearby galaxies 
    Subramaniam, A (Astronomical Society of India, 2007-06)
    We propose to identify the hot stellar population of the galactic globular clusters (GCs) using the TAUVEX. These stars can be easily identified in the core of the GCs where the crowding due to the main-sequence stars get ...
  • Further evidence for intra-night optical variability of radio-quiet quasars 
    Goyal, Arti; Gopal-Krishna; Sagar, R; Anupama, G. C; Sahu, D. K (Astronomical Society of India, 2007-06)
    Although well established for BL Lac objects and radio-loud quasars, the occurrence of intra-night optical variability (INOV) in radio-quiet quasars is still debated, primarily since only a handful of INOV events with good ...
  • TAUVEX---UV observations from geosynchronous orbit 
    Murthy, J; Safonova, M; Mohan, Rekhesh; Gopakumar, P (Astronomical Society of India, 2007-06)
    The T Observatory consists of three identical co-aligned telescopes operating in several bands in the 1200-3500, rmAA bandpass from geostationary orbit. The major science objectives of T are (a) searches for QSOs and AGNs ...
  • Spectroscopic properties of post-AGB stars 
    Parthasarathy, M (Cambridge University Press, 2006)
    A review of the spectroscopic properties of post-AGB stars is presented.
  • Compressional Alfvén surface waves with inclined magnetic fields 
    Satya Narayanan, A (Indian Association for the Cultivation of Science, 1996-12)
    The properties of the Alfvén compressional waves are discussed for a cold plasma when the magnetic field is inclined at an angle to the interface where there is a sharp change in the densities of the plasma. The condition ...
  • Parsec-scale radio morphology in Seyfert galaxies 
    Lal, D. V; Shastri, P; Gabuzda, D. C (The Astronomical Society of the Pacific, 2001)
  • Geomagnetic effect associated with X-ray flare from Sco X-1 
    Sastri, J. H; Murthy, B. S (Nature Publishing Group, 1975-09)
    The possibility is examined that an X-ray flare from Sco X-1, detected during a balloon flight in 1967, had a daytime geomagnetic effect. There was uncertainty as to the cause of the geomagnetic effect because of a ...
  • Reflection effect in close binaries 
    Srinivasa Rao, M (The Astronomical Society of the Pacific, 2003-01)
    The theoretical modeling of binary systems can be performed by considering realistic models which take into account the radiative transfer, hydrodynamics, reflection effect, temperature structure etc. Since the problem is ...
  • A simple model for coronal loops and their stability 
    Satya Narayanan, A (European Space Agency, 1999-12)
  • Radio emission of coronal shock waves 
    Benz, A. O; Thejappa, G (European Southern Observatory, 1988-08)
    The "backbone" emission of shock initiated coronal (metric) type II solar radio bursts is considered. The source has extremely narrow bandwidth and appears to be stationary in relation to the shock. The increasingly complete ...
  • Theoretical study of irradiation effects in close binaries 
    Srinivasa Rao, M; Varghese, B. A (Astronomical Observatory, 2009-06)
    The effect of irradiation is studied in a close binary system assuming that the secondary component is a point source, moving in a circular orbit. The irradiation effects are calculated on the atmosphere of the primary ...
  • Comet C/2004 Q2 (Machholz) 
    Sastri, J. H; Vasundhara, R; Kuppuswamy, K; Velu, C (International Astronomical Union, 2005-02)
  • A new band system of BiF molecule in the region λ6200-λ7000 
    Murthy, P. S; Rao, D. V. K; Reddy, Y. P; Rao, P. T (Taylor & Francis Group, 1975)
    A reinvestigation of the electronic spectrum of BiF, has revealed the presence of a new system of bands, degraded to longer wavelengths, in the region λ6200-λ7000 Aring. The band heads could be represented by the following ...
  • Night time geomagnetic effects of solar flares 
    Sastri, J. H (European Geophysical Society, 1975-07)
    A study of the normal run magnetogram data of two equatorial stations, Kodaikanal (Geo. Long. 77 deg 28 min E, Dip 3.5 deg N) and Huancayo (Geo. Long. 75 deg 20 min W, Dip 2.0 deg N), for a three year period (1969-1971), ...
  • The geomagnetic solar flare effect of 6 July 1968 and its implications 
    Sastri, J. H (European Geophysical Society, 1975-12)
    A study of the geomagnetic solar flare effect (SFE) of July 6, 1968, observed at five Indian magnetic observatories, lying in the longitude range 72-80 E, revealed that this SFE is characterized by a decrease in the ...
  • On the points of bifurcation along the sequence of rotating axisymmetric masses with magnetic fields 
    Kochhar, R. K (Indian Academy of Sciences, 1975-11)
    It is shown that the points of bifurcation belonging to the third harmonics along the sequence of Maclaurin spheroids viewed from an inertial frame are distinct from the corresponding points along the Maclaurin sequence ...
  • On the simultaneous existence of eastward and westward flowing equatorial electrojet currents 
    Rastogi, R. G (Indian Academy of Sciences, 1975-02)
    Experimental data on daily variations in the geomagnetic field are analyzed for evidence of counterflowing electrojets. In particular, the disappearance of the q type of Es layer (Es-q) and the appearance of blanketing-type ...
