  • Quasi-periodic spicule-like cool jets driven by Alfvén pulses 
    Singh, B; Srivastava, A. K; Sharma, K; Mishra, S. K; Dwivedi, B. N (Oxford University Press on behalf of Royal Astronomical Society, 2022-04)
    We perform a 2.5D magnetohydrodynamic simulation to gain a comprehensive understanding of the formation of spicule-like cool jets caused by initial transverse velocity pulses akin to Alfven´ pulses in the solar chromosphere. ...
  • Science from "Solar X-ray Spectrometer (SOXS)" - Proposed payload onboard Indian satellite 
    Jain, R; Rao, A. R; Deshpande, M. R; Dwivedi, B. N; Manoharan, P. K; Seetha, S; Vahia, M. N; Vats, H. O; Venkatakrishnan, P (Astronomical Society of India, 2000)
    It is proposed to fly a high spectral and temporal resolution "Solar X-ray Spectrometer (SOXS)" onboard Indian satellite to understand the mechanisms of energy release and particle acceleration in solar flares. The SOXS ...
  • Solar plasma line diagnostics from Ne IV, Na V and A1 VII ions 
    Dwivedi, B. N; Gupta, A. K; Mohan, A (Astronomical Society of India, 1998-12)
  • Spatial damping of compressional MHD waves in prominences 
    Singh, K. A. P; Dwivedi, B. N; Hasan, S. S (EDP Sciences, 2007-10)
    Aims.We study the spatial damping of linear compressional MHD waves in a homogeneous, isothermal, and unbounded prominence. Methods.We derive a general dispersion relation invoking the Newtonian radiation and turbulent ...
  • Sumer/soho 
    Dwivedi, B. N (Astronomical Society of India, 1998)
    The Solar and Heliospheric Observatory (SOHO), a project of international cooperation between ESA and NASA, was launched on December 2, 1995 and arrived at its operational location (the L1 Lagrangian point, 1.5X10 to the ...
