  • On type II solar radio bursts 
    Thejappa, G (Elsevier, 1986)
    The proposed model for the generation mechanism of type II solar radio bursts is based on the fact that a small fraction of ions is reflected from the supercritical shock front and tend to evolve into a 'ring' in the ...
  • On Zero-Point Fluctuations, the Cosmological Constant, and the Graviton Mass 
    Sivaram, C (The American Astronomical Society, 1999-08)
    Recently attempts have been made to link vacuum zero-point fields (ZPF), with a nonzero cosmological constant (Lambda), which is now treated as a cosmological free variable to be determined by observations. In another ...
  • Onboard Automated CME Detection Algorithm for the Visible Emission Line Coronagraph on ADITYA-L1 
    Ritesh Patel; Amareswari, K; Pant, v; Banerjee, D; Sankarasubramanian, K; Amit Kumar (Springer, 2018-07)
    ADITYA-L1 is India’s first space mission to study the Sun from the Lagrange 1 position. The Visible Emission Line Coronagraph (VELC) is one of seven payloads on the ADITYA-L1 mission, which is scheduled to be launched ...
  • Once in a blue moon: detection of bluing' during debris transits in the white dwarf WD 1145+017 
    Hallakoun, N; Xu, S; Maoz, D; Marsh, T. R; Ivanov, V. D; Dhillon, V. S; Bours, M. C. P; Parsons, S. G; Kerry, P; Sharma, S; Su, K; Sridharan, R|; Pravec, P; Kusnirak, P; Kucakova, H; Armstrong, J. D; Arnold, C (Oxford University Press on behalf of the Royal Astronomical Society, 2017-08)
    The first transiting planetesimal orbiting a white dwarf was recently detected in K2 data of WD 1145+017 and has been followed up intensively. The multiple, long and variable transits suggest the transiting objects are ...
  • One dimensional prominence model 
    Nagabhushana, B. S (The European Southern Observatory, 1998-05)
    Based on reasonable assumptions and mathematical approximations a one dimensional, analytical model for solar quiescent prominences is constructed, which is in both magneto-hydrostatic and thermal equilibrium. Thermal ...
  • One more explanation of superluminal motion 
    Krishan, V (Indian Academy Sciences, 1988-12)
    A model in which stimulated Raman scattering produces superluminal motion in extragalactic radio sources is examined. The scattering medium studied is a plasma whose position, density, and temperature determine the rate ...
  • One year of monitoring of the 2006 outburst in optical and low radio frequencies 
    Anupama, G. C (Astronomical Society of the Pacific, 2008-12)
    The evolution of the optical spectrum of RS Ophiuchi was monitored beginning 1 day since the 2006 outburst discovery to over a year after the outburst. The evolution of the spectrum is found to be similar to previous ...
  • One year of monitoring of the Type IIb supernova SN 2011dh 
    Sahu, D. K; Anupama, G. C; Chakradhari, N. K (Oxford University Press on behalf of the Royal Astronomical Society, 2013-07-21)
    Optical UBVRI photometry and low-resolution spectroscopy of the Type IIb supernova SN 2011dh in M51 are presented, covering the first year after the explosion. The light curve and spectral evolution are discussed. The early ...
  • One-third spectrum in large scale Hall-magnetohydrodynamic turbulence 
    Krishan, V; Mahajan, S. M (American Institute of Physics, 2004-11)
    In a recent study [H. Branover, A. Eidelman, and E. Golbraikh, ``On the universality of large-scale turbulence,'' Phys. Fluids 16, 845 (2004)] the properties of the large scale turbulence have been investigated theoretically ...
  • Onset of equatorial spread-f 
    Sastri, J. H; Murthy, B. S (European Geophysical Society, 1978)
  • Onset of equatorial spread-F during post-midnight period 
    Sastri, J. H (Indian Academy of Sciences, 1979-01)
  • Onset of Hydrodynamic Non-Equilibrium in Helmet Streamers 
    Venkatakrishnan, P (Kluwer Academic Publishers, 1996-06)
    The steady-state solar wind solution is examined for different geometries of the flow tube that mimics a helmet streamer. Onset of non-equilibrium is seen whenever the spatial variation of the flow geometry crosses critical ...
  • Oort and the comets 
    Bhatt, H. C (Indian Academy of Sciences, 1993-07-25)
  • The Ooty Summer Training Program 1990 
    Saikia, D. J; Salter, C. J; Banhatti, D. G; Ghosh, T; Gothoskar, P; Manoharan, P. K (Astronomical Society of India, 1991)
  • Ooty synthesis radio telescope - Design and performance 
    Sukumar, S et. al. (Astronomical Society of Indian, 1988)
    The principle, design and operational parameters of the Ooty synthesis radio telescope (OSRT) are described. It consists of thirteen elements including the Ooty Radio Telescope, which is divided into five parts. Operating ...
