  • Magnetic Field and Plasma Diagnostics for Solar Coronal Mass Ejections: A Case Study Using the Forward Modeling Approach 
    Liu, X; Tian, H; Torok, T; Gibson, S; Yang, Z; Li, W; Samanta, T (Springer Nature B.V., 2023-10)
    The proposed COronal Solar Magnetism Observatory (COSMO) Large Coronagraph (LC) will provide unique observations to study coronal mass ejections (CMEs) with its ability to diagnose the magnetic field and plasma properties ...
  • 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 ...
