  • Kameswara Rao, N (Astronomical Society of India, 2005-12)
    Some archeoastronomical aspects regarding the development of observational astronomy in India during prehistoric times are described. A plea is made for the preservation of megalithic monuments of possible astronomical ...
  • Ramadurai, S (Indian Institute of Astrophysics, 1988)
  • Sharma, D. K; Shyam, D; Sujatha, G (Indian Institute of Astrophysics, Bangalore, 1991)
    In this communication we describe a program which can ray trace through systems bounded by spherical/ aspheric surfaces together with the option to trace through media having graded index profile (GRIN) for one or more ...
  • Sujatha, E. R; Kumaravel, P; Rajamanickam, V. G (Springer, 2014-02)
    This study aims to demonstrate the application of a Bayesian probability-based weight of evidence model to map landslide susceptibility in the Tevankarai stream watershed, Kodaikkanal, India. Slope gradient, relief, aspect, ...
  • Shantikumar, N. S; Srivastava, A. K; Bagare, S. P; Singh, R. B; Kanawade, V. P; Dorjey, N (Springer, 2015-11)
    Optical and micro-physical features of aerosol are reported using Skyradiometer (POM-01L, Prede, Japan) observations taken from a high-altitude station Merak, located in north-eastern Ladakh of the western transHimalayas ...
  • Ghosh, S. K; Das, B; Rengarajan, T. N; Verma, R. P (Astronomical Society of India, 1993)
    Three image processing schemes, used for generating far-infrared (FIR) astronomical maps have been compared for their relative merits. Two of these schemes based on the maximum entropy method (MEM) have been developed at ...
  • Suryanarayana, G. S (Elsevier, 2022-07-01)
    Active region (AR) flux is released in the form of flares and Coronal Mass Ejections and a host of several other energetic events. The development of an AR is an indication of the accumulation of flux which reflects the ...
  • Narang, Nancy; Banerjee, D; Chandrashekhar, K; Pant, V (Springer, 2019-04)
    Recent dedicated Hinode polar region campaigns revealed the presence of concentrated kilogauss patches of the magnetic field in the polar regions of the Sun, which are also shown to be correlated with facular bright points ...
  • Narang, Nancy; Chandrashekhar, K; Pant, V; Banerjee, D (Cambridge University Press, 2018-02)
    Recent dedicated HINODE polar region campaign revealed the presence of concentrated kilogauss patches of magnetic field in the polar regions of Sun which are also shown to be correlated with facular bright points at the ...
  • Shelke, R. N; Pande, M. C (Astronomical Society of India, 1984-12)
    Association of coronal holes with large scale solar magnetic fields has been investigated. It is concluded that coronal holes always form in the large unipolar megnetic field patterns, and no specific polarity rule holds ...
  • Mandal, Sudip; Chatterjee, Subhamoy; Banerjee, D (IOP Publishing, 2017-02-01)
    Plages are the magnetically active chromospheric structures prominently visible in the Ca ii K line (3933.67 Å). A plage may or may not be associated with a sunspot, which is a magnetic structure visible in the solar ...
  • Uddin, W; Pande, M. C; Shelke, R. N (Astronomical Society of Indian, 1986-06)
    A 'twisting index' is defined, assuming that flares tend to occur in highly sheared magnetic fields which also lead to a twisting of magnetic neutral lines in complex active regions. The correlation of this twisting index ...
  • Mandal, Sudip; Chatterjee, Subhamoy; Banerjee, D (IOP Publishing, 2018-09)
    We analyze the long-term behavior of the supergranule scale parameter, in active regions (ARs) and quiet regions (QRs), using the Kodaikanal digitized data archive. This database provides century-long daily full ...

    We present preliminary asteroseismic results from Kepler on three G-type stars. The observations, made at one-minute cadence during the first 33.5d of science operations, reveal high signal-to-noise solar-like oscillation ...
  • Audard, N; Brown, T. M; Christensen-Dalsgaard, J; Frandsen, S; Kjeldsen, H (Astronomical Society of India, 1996)
    Combining classical and seismological data permits one to perform a calibration of stars, and therefore to improve the estimate of their fundamental parameters. We present preliminary results of the calibration of stars ...
