Transition region counterpart of a moving magnetic feature

Lin, C. -H; Banerjee, D; O'Shea, E; Doyle, J. G (EDP Sciences, 2006-12)

this which we seek to address in this work. Aims.In this work we aim to investigate the chromospheric and transition-region dynamics associated with a moving magnetic monopole by using spectral time-series and ...
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 ...
Variation of line widths in polar off-limb regions

Banerjee, D; O'Shea, E; Doyle, J. G (European Space Agency, 2005-12)

Using measurement from the Coronal Diagnostic Spectrometer (CDS) on board SOHO we seek to examine the relative roles of radiative and Collisional excitation in regions far off-limb at the Northern pole of the sun. We study ...
Very long period activity at the base of solar wind streams

Popescu, M. D; Banerjee, D; O`Shea, E; Doyle, J. G; Xia, L. D (EDP Science, 2005-11)

Using time series data of spectral lines originating from a wide range of temperatures in the solar transition region, above a polar coronal hole, from SUMER (Solar Ultraviolet Measurements of Emitted Radiation) on SoHO ...
