  • On the coupling between lower and upper atmosphere of the Sun 
    Samanta, T (Indian Institute of Astrophysics, 2017-01)
    The thesis is focused on the study of the small-scale transients and waves as seen in the different layers of the solar atmosphere and the coupling between the different layers. The unique high resolution data obtained ...
  • Propagating disturbances along fan-like coronal loops in an active region 
    Mandal, Sudip; Samanta, T; Banerjee, D; Krishna Prasad, S; Teriaca, L (IOP Publishing, 2015-11)
    Propagating disturbances are often observed in active region fan-like coronal loops. They were thought to be due to slow mode magnetohydrodynamic waves based on some of the observed properties. However, recent studies ...
  • Propagating disturbances in the solar corona and spicular connection 
    Samanta, T; Pant, V; Banerjee, D (IOP Publishing, 2015-12-10)
    Spicules are small, hairy-like structures seen at the solar limb, mainly at chromospheric and transition region lines. They generally live for 3–10 minutes. We study these spicules in a south polar region of the Sun with ...
  • Quasi-periodic oscillation of a coronal bright point 
    Samanta, T; Banerjee, D; Tian, H (IOP Publishing, 2015-06-20)
    Coronal bright points (BPs) are small-scale luminous features seen in the solar corona. Quasi-periodic brightenings are frequently observed in the BPs and are generally linked with underlying magnetic flux changes. We study ...
  • Searching for a Solar Source of Magnetic-Field Switchbacks in Parker Solar Probe’s First Encounter 
    Pablos, D. de; Samanta, T; Badman, S. T; Schwanitz, C; Harra, L. K; Petrie, G; Mac Cormack, C; Mandrini, C. H; Raouafi, N. E; Martinez Pillet, V; Velli, M (Springer Nature, 2022-07)
    Parker Solar Probe observations show ubiquitous magnetic-field reversals closer to the Sun, often referred to as “switchbacks”. The switchbacks have been observed before in the solar wind near 1 AU and beyond, but their ...
