  • Magnetic and velocity properties of G-band bright points around a pore 
    Rangarajan, K. E; Sankarasubramanian, K; Nagaraju, K (Astronomical Society of the Pacific, 2009-06)
    Physical properties of G-band bright points (GBPs) surrounding a pore are studied using observations spanning from photosphere to chromosphere. The magnetic field strengths obtained in these bright points are of the order ...
  • The effect of polar magnetic sub-storms on the equatorial sporadic E 
    Rastogi, R. G (Indian Academy of Sciences, 1973)
    It is known that equatorial sporadic E disappears at night when dynamo field is east to west. During some DP/sub2 type magnetic sub-storms, which cause a depression of the geomagnetic horizontal field at the equator, the ...
  • Equatorial sporadic e and cross-field instability 
    Rastogi, R. G (Indian Academy of Sciences, 1972-05)
    The occurrence of sporadic E at an equatorial station during magnetically quiet daytime conditions corresponds almost exactly to the time during which the horizontal component of the earth’s magnetic field is above the ...
  • Geomagnetic crochets associated with proton flares 
    Sastri, J. H; Murthy, B. S; Karunakaran, D (National Institute of Science Communication And Information Resources, 1975-03)
  • A detailed study of the geomagnetic storm of 8-10 March 1970 
    Balakrishnan, T. K; Varadarajan, R; Singh, S. B; Karunakaran, D; Aleem, P. S. M (National Institute of Science Communication And Information Resources, 1973-03)
    A comprehensive study of the geomagnetic oscillations during the storm of 8 – 10 March 1970 is made using data obtained from equatorial stations. The oscillation characteristics during the three main phases of the storm ...
  • Solar eclipse will only be partially visible in state 
    The Hindu (The Hindu, 2009-07-21)
  • Scientists' reasoning eclipses soothsayers' doomsday claims 
    Deccan Herald (Deccan Herald, 2009-07-21)
  • Magnetic showers in space 
    Sivaram, C (Deccan Herald, 2006-12-19)
  • Need to promote international co-operation in space 
    The New Indian Express (The New Indian Express, 2006-11-28)
  • On the clustering of GRBs on the sky 
    Sethi, S. K; Bhargavi, S. G; Greiner, J (American Institute of Physics, 2000-09)
    The two-point correlation of the 4th (current) BATSE catalog (2494 objects) is calculated. It is shown to be consistent with zero at nearly all angular scales of interest. Assuming that GRBs trace the large scale structure ...
  • Observing the GRB remnants 
    Bhargavi, S. G; Cowsik, R; Perna, R (Astronomical Society of the Pacific, 2004-06)
    Following the predictions of Perna, Reymond & Loeb (2000) we have proposed an observational program to search for the GRB remnants in nearby galaxies using the telescopes of Indian Institute of Astrophysics, Bangalore. We ...
  • Scientist par excellence 
    Deccan Herald (Deccan Herald, 2002-03-05)
  • Photospheric field gradient in the neighbourhood of quiescent prominences 
    Nagabhushana, B. S; Gokhale, M. H (Springer, 1990)
    We have determined statistically the horizontal gradiant of the vertical magnetic field in the neighbourhood of filaments inside and outside the active regions during a few months in 1981 and in 1984. The results show that ...
  • Indian Astronomical Observatory, Hanle 
    Cowsik, R; Srinivasan, R; Prabhu, T (Astronomical Society of the Pacific, 2002)
    The Indian Institute of Astrophysics (IIA) Bangalore has established the Indian Astronomical Observatory (IAO) at an altitude of 4500 m above mean sea level atop Mt. Saraswati, Hanle, Changthang Ladakh, India. The birth ...
  • Hot post-AGB stars 
    Parthasarathy, M; Gauba, G; Fujii, T; Nakada, Y (Kluwer Academic Publishers, 2001-08)
    From the study of IRAS sources with far-IR colors similar to planetary nebulae (PNe), several proto-planetary nebulae with hot (OB) post-AGB central stars have been detected. These stars form an evolutionary link between ...
  • Searching for GRB remnants in nearby galaxies 
    Bhargavi, S. G; Rhoads, J; Perna, R; Feldmeier, J; Greiner, J (American Institute of Physics, 2004-09)
    Gamma Ray Bursts (GRBs) are expected to leave behind GRB remnants, similar to how ``standard'' supernovae (SN) leave behind SN remnants. The identification of these remnants in our own and in nearby galaxies would allow a ...
  • Networking of astronomy libraries and resource sharing in India 
    Vagiswari, A; Louis, C (Astronomical Society of the Pacific, 1998)
    A brief description of the proposed networking of astronomy libraries in India is given. Three models are identified which may be introduced successively as and when all eight libraries acquire necessary software and hardware.
  • Growing importance of conference proceedings in astronomy and astrophysics and its impact on collection development 
    Vagiswari, A; Louis, C (Elsevier, 1995)
    This paper analyses the change in the referencing pattern among the astronomers. There has been an increase in the number of conference proceedings (CP) during the last 10 years. In astronomy alone there were around 131 ...
  • Lakhs of asteroids and still counting 
    Sivaram, C (Deccan Herald, 2009-07-14)
  • Solar eclipse on July 22
