Scientific Aims

We will systematize our knowledge of the emission of solar flares in the THz range (submillimeter wavelengths). This is essentially a new field of solar flare research, with substantial ambiguities of interpretation but potentially great significance because of the implications for high-energy particle acceleration. It is also a timely topic due to the potential for future observations in the THz domain with the new instrumentation at SST (the Solar Submillimer-wave Telescope) and ALMA (the Atacama Large Millimeter Array) and proposed space instrumentation. We therefore anticipate good discussions of current observations, vigorous debate of the theories in the context of the broad coverage of solar flares now available at other wavelengths, and the potential of the new instruments to address the questions arising. The output of the team will be an overview paper setting out the properties of the existing observations and their interpretations, and goals for new observations.

Paper draft:

The beginnings of a paper are on this directory (updated 6-Sep-2010)

Editorial rotation and publication plan

We have decided to experiment with a new scheme for contributions to the overview paper. In the following list each author has been assigned a specific week for input to the manscript. This could either be by copying the files and emailing any new ones to Hugh and Sa"m, or else by marking up a .pdf and sending that. We intend to update the working directory each weekend during this cycle and send an informational email out.
