Spectroscopy and Imaging of Quiescent and Eruptive Solar Prominences from Space
The whole team!
We are pleased to announce the forthcoming publication by Space Science Reviews of a special issue dedicated to solar prominence physics. Two review papers present our current understanding and the outstanding issues in the following areas:
Paper I: Spectral Diagnostics and Non-LTE Modelling - N. Labrosse, P. Heinzel, J.-C. Vial, T. Kucera, S. Parenti, S. Gunár, B. Schmieder, and G. Kilper. http://arxiv.org/abs/1001.1620
The paper discusses topics relating to:
- the spectral inversion for the cool prominence plasma and for the prominence-to-corona transition region,
- determination of bulk motions and mass,
- basics of radiative transfer for spectral diagnostics based on optically thick lines, and
- non-LTE modelling of prominences.
Paper II: Magnetic Structure and Dynamics - D.H. Mackay, J.T. Karpen, J.L. Ballester, B. Schmieder and G. Aulanier. http://arxiv.org/abs/1001.1635
The paper discusses recent advances in our understanding of:
- prominence magnetic structure (observations and theory),
- formation and dynamics of prominence plasmas,
- MHD waves in prominences, and
- formation and large-scale patterns of filament channels.
ISSI prominence team meeting pages
The meetings and wiki pages are in the private area (restricted access).
Purpose
Our International Team spans a wide range of expertise in order to make
progress on the understanding of solar prominences. The Team consists
of 11 members whose research interests combine data analysis and
interpretation, radiative transfer modelling, and modelling of the
magnetic field and plasma. We will meet at ISSI to discuss the latest
developments in these fields, interpret existing space observations,
set up new observational programmes using space instrumentation, and
decide modelling strategies to be carried out between the meetings. The
expected outcome of the proposed research is a better understanding of
the formation processes of solar prominences, of the physical
conditions necessary for the stability of quiescent prominences, and of
the mechanisms leading to prominence activation and eruption.

Subsistence
A great deal of work is done thanks to the good restaurants we can go to in the evening as a group of 10 or more people! Here are a few that we tried and liked, for future reference for ourselves and other teams...
