  • Sivaram, C; Krishan, V (Gordon and Breach Science Publishers, 1983)
    The phenomenon of neutron-antineutron oscillations, recently proposed as a novel consequence of grand unified theories, permits limits to be placed on any primordial field present during the nucleosynthetic stage of the ...
  • Sivaram, C; Krishan, V (Nature Publishing Group, 1982-09)
    The recent detection1,2 of an antiproton/proton (/p) ratio at energies much less than 1 GeV is several orders of magnitude above that predicted for production from primary cosmic ray collisions. It is well recognized that ...
  • Konar, S; Bagchi, Manjari; Bandyopadhyay, Debades; Banik, Sarmistha; Bhattacharya, D; Bhattacharyya, S; Gangadhara, R. T; Gopakumar, A; Gupta, Y; Joshi, B. C; Maan, Yogesh; Maitra, Chandreyee; Mukherjee, D; Pai, Archana; Paul, B; Ray, A; Sutaria, F. K (Indian Academy of Sciences, 2016-12)
    It is an exceptionally opportune time for astrophysics when a number of next-generation mega-instruments are poised to observe the Universe across the entire electromagnetic spectrum with unprecedented data quality. The ...
  • Kundt, W (Astronomical Society of India, 2001)
    An unconventional survey is presented of the observable properties of neutron stars and of all astrophysical phenomena possibly related to them, such as their pulsing, clock irregularities, bursting, flickering, and ...
  • Lavakare, J. V (Astronomical Society of India, 1977-09)
  • Datta, B (World Scientific, 1995)
    Neutron stars are extremely compact stellar objects, with density that of atomic nucleus and higher. The composition of neutron stars is believed to be mostly neutrons, with admixtures of protons, electrons and perhaps ...
  • Birdie, C (IATUL (International Association of Scientific and Technological Universities Libraries), 2002)
    The quantity of information purchased by libraries has been declining in recent years due to the price escalation of scholarly publications. Libraries are exploring new ways to provide more information with less budget. ...
  • Prasad, L; Chandra, S (Astronomical Society of India, 1992)
    The study presents a novel approach for the inclusion of the effect of gravity in the magnetohydrostatic equilibrium in coronal arcades, in which the magnetic lines of force are unaffected whereas the pressure isobars are ...
  • Chinnappan, V (Indian Institute of Astrophysics, 2006-08)
    Atmospheric turbulence is the main cause of image degradation and poor resolution at the focal plane of a perfectly made optical telescope. It is necessary to make corrective measures to improve the optical wave-front, ...
  • The Hindu (The Hindu, 2009-11-30)
  • Madhwani, P. P; Manchanda, R. K (Astronomical Society of India, 2000)
    The tracking of an astronomical object requires continuous updating of the look angles in azimuth and zenith. The mathematical calculation of these angles needs the position coordinates (latitude and longitude) of the place ...
  • 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 ...
  • Deccan Herald (Deccan Herald, 2019-10-16)
  • Sivaram, C; Arun, K (Bentham Open, 2011-05)
    About one-fourth of the universe is thought to consist of dark matter. Yet there is no clear understanding about the nature of these particles. Commonly discussed dark matter candidates includes the so called WIMPs or ...
  • Manna, A; Chakrabarti, S; Mukhopadhayay, P. K (Astronomical Society of India, 2002)
    The high energy gamma ray telescopes being set up by the Bhabha Atomic Research Institute Centre (BARC) at Mt. Abu, Rajasthan, as part of the GRACE project, require a very large number (~ 1000) of programmable high voltage ...
  • Vasundhara, R; Arlot, J. E; Descamps, P (International Astronomical Union, 1996)
    New constants for sampson-Lieske theory of the Galilean satellites have been derived using 6360 individual photographic positions (1891-1990) and 438 pseudo astrometric positions from mutual occulations during 1973,1979,1985 ...
  • Das, T. K; Nag, T. K (Astronomical Society of India, 2003)
    A new cycle of about 5.5 years has been invoked in case of the periodicity in solar flare indices. As there exists no instrumental technique for measuring directly the energy output of an optical flare, the energy emitted ...
  • Palacios, A; Jasniewicz, G; Masseron, T; Thevenin, F; Itam-Pasquet, J; Parthasarathy, M (EDP Sciences, 2016-03)
    Context. Weak G -band (wGb) stars are a very peculiar class of red giants; th ey are almost devoided of carbon and often present mild lithium enrichment. Desp ite their very puzzling abundance pa tterns, very few ...
  • Srinivasan, R; Naidu, B. N (Astronomical Society of the Pacific, 1997-01)
    The Carl-Zeiss 1-meter telescope at Vainu Bappu Observatory uses synchro transmitters as angular transducers in a 3-stage geared train for the two axes coordinate display system. Synchro receivers are used in the console ...
  • Ebenezer, E; Ramesh, R; Subramanian, K. R; Sundararajan, M. S; Sastry, Ch. V (EDP Sciences, 2001-03)
    A new digital spectrograph for obtaining a dynamic spectrum of radio burst emission from the Sun in the frequency range 30-80 MHz has been recently commissioned at the Gauribidanur Radio Observatory (Lat: 13degr ...
