  • GONG site evaluation program at Udaipur Solar Observatory 
    Ambastha, A; Bhatnagar, A; Jain, R; Srivastava, N; Gupta, S; Sharma, R; Agrawal, G (Astronomical Society of India, 1991)
    The Global Oscillations Network Group (GONG) project to study the internal structure and dynamic of the sun is discussed. The GONG project will measure waves that penetrate throughout the sun's core. Power spectra of the ...
  • Halpha, microwave and hard X-ray observations of the two-ribbon flare of 1980 April 3 
    Jain, R (Astronomical Society of India, 1993-06)
    The Halpha observations of a class 2B two ribbon flare, associated with exceptional hard X-ray and microwave emissions, are presented and discussed. The observational relationship suggests that the gradient of the magnetic ...

K; Ghosh, S (IOP Publishing, 2022-11)
    Nuclear astrophysics is a field at the intersection of nuclear physics and astrophysics, which seeks to understand the nuclear engines of astronomical objects and the origin of the chemical elements. This white paper ...
  • Observations of the Interaction of Acoustic Waves and Small-scale Magnetic Fields in a Quiet Sun 
    Pradeep Chitta, L; Jain, R; Kariyappa, R; Jefferies, S. M (IOP Publishing, 2012-01-10)
    The effect of the magnetic field on photospheric intensity and velocity oscillations at the sites of small-scale magnetic fields (SMFs) in a quiet Sun near the solar disk center is studied. We use observations made by the ...
  • On the power and frequency of p-modes in sunspots 
    Kumar, B; Tripathy, S. C; Jain, R; Deshpande, M. R (Astronomical Society of India, 2000)
    A time series of GONG Dopplergrams has been used to measure the velocity fluctuations in the sunspot and quiet photosphere simultaneously. The power spectrum analysis shows that the power of the predominant p-mode is reduced ...
  • Processing electronics instrumentation for the low energy detector of Solar X-ray Spectrometer (SOXS) experiment 
    Umapathy, C. N; Sharma, M. R; Solanky, C; Kulkarni, R; Shah, A. B; Vadher, N. M; Jain, R; Jain, A. K; Sreekumar, P (Astronomical Society of India, 2001)
