  • 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 MHD waves in coronal holes 
    Banerjee, D; Teriaca, L; Gupta, G. R (Springer, 2011-07)
    Coronal holes are the coolest and darkest regions of the upper solar atmosphere, as observed both on the solar disk and above the solar limb. Coronal holes are associated with rapidly expanding open magnetic fields and the ...
  • Propagating waves in polar coronal holes as seen by SUMER & EIS 
    Banerjee, D; Teriaca, L; Gupta, G. R; Imada, S; Stenborg, G; Solanki, S. K (EDP Sciences, 2009-06)
    Context: To study the dynamics of coronal holes and the role of waves in the acceleration of the solar wind, spectral observations were performed over polar coronal hole regions with the SUMER spectrometer on SoHO and the ...
  • Spectroscopic observations of propagating disturbances in a polar coronal hole: evidence of slow magneto-acoustic waves 
    Gupta, G. R; Teriaca, L; Marsch, E; Solanki, S. K; Banerjee, D (EDP Sciences, 2012-10)
    Aims. We focus on detecting and studying quasi-periodic propagating features that have been interpreted in terms of both slow magneto-acoustic waves and of high-speed upflows. Methods. We analyzed long-duration spectroscopic ...
  • Transition region small-scale dynamics as seen by SUMER on SOHO 
    Teriaca, L; Banerjee, D; Falchi, A; Doyle, J. G; Madjarska, M. S (EDP Sciences, 2004-12)
    High spectral, spatial and temporal resolution UV observations of the quiet Sun transition region show a highly structured and dynamical environment where transient supersonic flows are commonly observed. Strongly non-Gaussian ...
