The aim of the proposed workshop is to provide an opportunity for a consolidated group of international collaborators to meet for 4 days, in order to make progress in their collaborative work.
The topics addressed are solar wind radial expansion, heating, acceleration and energy transport, as indicated by the workshop name, SOlar Wind Heating, Acceleration & Transport (SoWhat). We’ll be discussing the large-scale structure of the solar wind, its origin in relation to coronal structures, the non-thermal behavior of charged particles, and physical processes such as magnetic reconnection and turbulence in space plasmas.

The team of participants includes experts in space data processing (LESIA, Imperial College, SSL) and users of numerical codes developed at LESIA in the past (“expanding box”, “hybrid”, “kinetic-BiCoP”) and now shared with various European institutes (Prague, Florence, London, UCLA).
The workshop will therefore be an opportunity to consolidate existing collaborations between these teams, start new joint projects and finalize work in progress between the various participants. To this end, the planned format is a combination of scientific presentations, open discussions and parallel working groups; a format made possible by the resources made available at the Centre Jules Janssen.
The preliminary team of participants includes a dozen international researchers, members of LESIA’s HPA cluster, and PhD students and post-docs from LESIA, Prague, Florence and London.

In the international context, this proposal comes at a very active time for the heliospheric community, thanks to recently launched space missions that are studying the Sun and solar wind like never before (NASA/Parker Solar Probe and ESA/Solar Orbiter). Workshop participants are directly involved in these missions (including PIs and CoIs from various on-board instruments) and this meeting will also be an opportunity to update our theoretical models for these missions.

Finally, the presence of students on the team will enable them to benefit from interactions with several researchers who are experts in the field of simulations and observations. The workshop may also give them the opportunity to build new collaborations to be exploited during or after their thesis.
