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…
The Helium spectrum in erupting solar prominences
Nicolas Labrosse, Pierre Gouttebroze, Jean-Claude Vial
Even quiescent solar prominences may become active and sometimes erupt. These events are occasionally linked to coronal mass ejections. However we know very little about the plasma…
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,…
The abundances of nitrogen-containing molecules during pre-protostellar collapse
D. R. Flower, G. Pineau des Forets, C. M. Walmsley
We have studied the chemistry of nitrogen--bearing species during the initial stages of protostellar collapse, with a view to explaining the observed longevity of N2H+ and NH3 and…
