  • Mitra, S; Priestley, K; Gaur, V. K; Rai, S. S (Seismological Society of America, 2006-12)
    We use seismograms from regional earthquakes recorded on digital seismographs in peninsular India to determine the frequency-dependent Q of Lg for the Indian platform. We measure Lg attenuation by determining the decay of ...

  • Nagaraju, K; Phanindra, D. V. S; Krishna Prasad, S; Shankar Rao, D. S; Sreekumar, P (SPIE-The International Society for Optical Engineering, 2018-07-06)
    In a dual-frequency liquid crystal (DFLC), when the frequency of the applied voltage is more than a critical value (fc), the dielectric anisotropy of the material changes from positive to negative. This causes the director ...
  • Ravindra, B; Prabhu, K; Rangarajan, K. E; Bagare, S. P; Singh, J; Kemkar, P. M. M; Thulasidharen, K. C; Gabriel, F; Selvendran, R (IOP Publishing, 2016-08)
    This paper reports on the installation and observations of a new solar telescope installed on 2014 October 7 at the Kodaikanal Observatory. The telescope is a refractive type equipped with a tunable Lyot Hα filter. A CCD ...
  • Gokhale, M. H (Indian Institute of Astrophysics, Bangalore, 1977)
    It is conceviable that the periodic reversal of the Sun'd large-scale magnetic field and the concentration of the field in strong, thin flux tubes on small scales could bith result from the following likely processes near ...
  • Gokhale, M. H (Indian Institute of Astrophysics, Bangalore, 1977)
    For a satisfactory understanding of the solar magnetic phenomena it may be advantageous first to interrelate phenomenologically observations involving different scales of length and time and in different layers of the solar ...
  • Sivaram, C (Springer, 1994-12)
    A unified approach to fundamental interactions as explored earlier is further elaborated and its consequences for the early universe studied especially in connection with the energy dependence of the coupling constants.

  • Carraro, G; Subramaniam, A; Janes, K. A (Royal Astronomical Society, 2006-09)
    In this paper, we present the first BV I CCD photometry of six overlooked old open clusters (Berkeley 44, NGC 6827, Berkeley 52, Berkeley 56, Skiff 1 and Berkeley 5) and derive estimates of their fundamental parameters by ...
  • Gehrels, Tom (Astronomical Society of India, 1984-03)
    Planetesimals are intermediate stages, in the kilometer size range between interstellar matter and large bodies such as planets and stars. Planetesimals can still be studied in the form of asteroids although they have been ...
  • Subramanian, P; Becker, P. A (Springer, 2006-08)
    We reexamine the energetics of nonthermal-electron acceleration in solar noise storms. A new result is obtained for the minimum nonthermal-electron number density required to produce a Langmuir-wave population of sufficient ...
