  • Forbush decreases and turbulence levels at coronal mass ejection fronts 
    SUBRAMANIAN, PRASAD; Antia, H.M.; Dugad, S. R.; Goswami, U.D.; Gupta, S. K.; Hayashi, Y.; Ito, N.; Kawakami, S.; Kojima, H.; Mohanty, P.K.; Nayak, P.K.; Nonaka, T.; Oshima, A.; Sivaprasad, K.; Tanaka, H.; Tonwar, S.C. (EDP Sciences, 2009-02)
    Aims. We seek to estimate the average level of MHD turbulence near coronal mass ejection (CME) fronts as they propagate from the Sun to the Earth. Methods. We examined the cosmic ray data from the GRAPES-3 tracking muon ...
  • Characterizing the specific energy and pressure in near-Earth magnetic clouds 
    BHATTACHARJEE, DEBESH; SUBRAMANIAN, PRASAD; Vourlidas, Angelos; Nieves-Chinchilla, Teresa; Thejaswi, Niranjana; Sachdeva, Nishtha (EDP Sciences, 2023-01)
    Context. The pressure and energy density of the gas and magnetic field inside solar coronal mass ejections (in relation to that in the ambient solar wind) is thought to play an important role in determining their dynamics ...
  • Turbulence and Anomalous Resistivity inside Near-Earth Magnetic Clouds 
    BHATTACHARJEE, DEBESH; SUBRAMANIAN, PRASAD; Nieves-Chinchilla, Teresa; Vourlidas, Angelos (Oxford University Press, 2023-01)
    We use in-situ data from the Wind spacecraft to survey the amplitude of turbulent fluctuations in the proton density and total magnetic field inside a large sample of near-Earth magnetic clouds (MCs) associated with coronal ...
