  • Bhargava, B. N; Kasiviswanathan, G. A (Indian Meteorological Department, 1966)
    A simple portable proton precession magnetometer designed and constructed for Kodaikanal Observatory is described. Except for the signal amplifier, the instrument is transistorized. The accuracy of measurement of absolute ...
  • Bhattacharjee, P; Gupta, N (Elsevier, 2003-11)
    The detectability of a possible ``high'' energy (>100 GeV) component of gamma ray bursts (GRBs) using AMANDA/ICECUBE large area muon detectors is examined within the context of a specific model of such high energy gamma ...
  • Ren, Bin B; Benisty, Myriam; Ginski, Christian; Tazaki, Ryo; Wallack, Nicole L; Milli, Julien; Garuf, Antonio; Bae, Jaehan; Facchini, Stefano; Menard, Francois; Pinilla, Paola; Swastik, C; Teague, Richard; Wahhaj, Zahed (EDP Sciences, 2023-12)
    Context. The diverse morphology among protoplanetary disks may result from planet-disk interactions, suggesting the presence of planets undergoing formation. The characterization of disks can provide information on the ...
  • Bane Kshitij, Suhas Trupti; Barve, Indrajit V; Gireesh, G. V. S; Kathiravan, C; Ramesh, R (SPIE-The International Society for Optical Engineering, 2022-01)
    A prototype for dedicated observations of pulsars and other astrophysical transients in the frequency range of 50 to 80 MHz has been recently commissioned in the Gauribidanur Radio Observatory near Bangalore in India. ...
  • Gangadhara, R. T (The University of Chicago Press, 2004-07-01)
    We assume that relativistic sources moving along dipolar magnetic field lines emit curvature radiation. The beamed emission occurs in the direction of tangents to the field lines, and to receive it, the sight line must ...
  • Gangadhara, R. T (Springer Netherlands, 2008)
    Pulsar radio emission is belived to come from relativistic plasma accelerated along the dipolar magnetic field lines in pulsar magnetosphere. The beamed emission by relativistic sources occur in the direction of tangents ...
  • Sastry, Ch. V; Krishan, V; Subramanian, K. R (Indian Academy of Sciences, 1981-03)
    Observations on the pulsation pattern in the time profile of short duration solar radio bursts at decametre wavelengths are presented. The pulsations are found to be present predominantly in the saturation phase of the ...
  • Das, G. C (D. Reidel Publishing Co., 1980-08)
    A method of finding physical parameters by studying the pulses in the sun is discussed. Consideration is given to an ideal highly relevant model which could exist in the sun with the effects of ionization, due to which ...
  • Bhatt, H. C; Jain, S. K; Sagar, R (European Southern Observatory, 1998-03)
    Optical linear polarization measurements of association members and field stars in the region of the Puppis OB III association are presented. The association members are found to have larger values of polarization than the ...
  • Parthasarathy, M; Jasniewicz, G; Thevenin, F (Springer, 2019-01)
    HD 179821 is classified as G5 Ia star. From the IRAS colors and spectral energy distributions it was classified as a post-AGB star. But some studies classify it as a massive (30 to 19 M⊙) post-red supergiant evolving to ...
  • Perrine, T. M; Chaudhuri, R. K; Freed, K. F (John Wiley & Sons, Inc., 2005-10)
    Simple and quadratic Padé resummation methods are applied to high-order series from multireference many-body perturbation theory (MR-MBPT) calculations using various partitioning schemes (Møller-Plesset, Epstein-Nesbet, ...
  • Safonova, M; Mathur, Archana; Basak, Suryoday; Bora, Kakoli; Agrawal, Surbhi (Jointly published by EDP Sciences, Società Italiana di Fisica and Springer Berlin Heidelberg, 2021-09)
    What is habitability? Can we quantify it? What do we mean under the term habitable or potentially habitable planet? With estimates of the number of planets in our Galaxy alone running into billions, possibly a number greater ...
  • Bhattacharyya, J. C (Saha Institute of Nuclear Physics, 2017-07)
    Several new questions of quantitatively estimating physical conditions on astronomical bodies had opened up after formulation of Saha Ionization Equation. The article first reviews the step by step progress in ...
  • Acker, A; Parthasarathy, M; Leindecker, W; Koeppen, J; Stenholm, B (International Astronomical Union, 1997)
  • Saxena, A. K (Optical Society of America, 1979)
    A quantitative test for the evaluation of surface figures of concave aspheric surfaces using a Babinet compen-sator is reported. A theoretical estimate of the sensitivity is 0.002X for a minimum detectable phase change of ...
  • Basu, R; Ravindran, V (Indian Academy of Sciences, 2003-02)
    We discuss potential problems in hadronic physics. Recent developments are reviewed and possible future studies in some interesting areas which are underway are highlighted
  • Unnikrishnan, C. S (Springer, 2001-09)
    The Einstein-Podolsky-Rosen (EPR) nonlocality puzzle has been recognized as one of the most important unresolved issues in the foundational aspects of quantum mechanics. We show that the problem is more or less entirely ...
  • Srikanth, R (Indian Academy of Sciences, 2001-11)
  • de Sabbata, V; Sivaram, C; Borzeszkowski, H. H. V; Treder, H. J (John Wiley & Sons, Inc., 1991)
    It is shown that in gravitational theories with torsion one is led to commutation rules corresponding to Landau-Peierls type uncertainty relations.
  • Smitha, H. N; Nagendra, K. N; Stenflo, J. O; Bianda, M; Ramelli, R (IOP Publishing, 2014-10-10)
    The Sc II 4247 Å line formed in the chromosphere is one of the lines well known, like the Na I D2 and Ba II D2, for its prominent triple-peak structure in Q/I and the underlying quantum interference effects governing it. ...
