\subsection{List of possible science themes (unsorted)}  \subsubsection{Bring the \textbf{sun} back into "Cool Stars, stellar systems and the sun"}  In recent years, the communities of cool stars and solar physics have more and more divirged, diverged,  as the stellar astronomers have concentrated on the great zoo of exoplanets, while solar astronomers have increasingly detailed spectral, spatial and temporal resolution in their observations that has simply no comparison in stellar astrophysics. Given the strong solar research groups at the CfA, a workshop in Cambrdige is uniquely suited to set an agenda with a strong solar component, that will attract solar astronomers to be presenters and workshop participants. Despite the different fashions in both fields, the old guiding principle that we understand cool stars from looking at the solar example in detail, and that we understand the sun by comparing to a more complex sample with e.g. different ages (sun in time), masses, or abundances is true. Even people talking about potential Star-planet-interaction always come back to the solar example. The last few CS workshops had invited solar talks, but very few participants from the solar community, thus there were no solar posters, no contributed solar talks and no discussion in the corridors with solar physics experts. Thus, I advocate for a 1-day theme focussed focused  entirely on the sun, strong enough in solar speakers and rooted in the CfA solar groups to draw attendance from the solar community worldwide.
