O VI and H_2 Lines in Sunspots
Nicolas Labrosse, Huw Morgan, Shadia Rifai Habbal +1
Sunspots are locations on the Sun where unique atmospheric conditions prevail. In particular, the very low temperatures found above sunspots allow the emission of H_2 lines. In thi…
Spectral Diagnostics of Active Prominences
Nicolas Labrosse, Pierre Gouttebroze, Jean-Claude Vial
Active prominences exhibit plasma motions, resulting in difficulties with the interpretation of spectroscopic observations. These solar features being strongly influenced by the ra…
Plasma diagnostic of a solar prominence from hydrogen and helium resonance lines
N. Labrosse, J. -C. Vial, P. Gouttebroze
We present the first comparison of profiles of H et He resonance lines observed by SUMER with theoretical profiles computed with our non-LTE radiative transfer code. We use the H I…
Effect of motions in prominences on the helium resonance lines in the extreme ultraviolet
Nicolas Labrosse, Pierre Gouttebroze, Jean-Claude Vial
We aim at studying the effect of radial motions on the spectrum emitted by moving prominences in the helium resonance lines and at facilitating the interpretation of observations,…
