  About 2 years ago, back in 2009, the first CoRoT Symposium was the occasion
to present and discuss unprecedented data revealing the behaviour of stars at
the micromagnitude level. Since then, the observations have been going on, the
target sample has enriched and the work of analysis of these data keeps
producing first rank results.
  These analyses are providing the material to address open questions of
stellar structure and evolution and to test the so many physical processes at
work in stars. Based on this material, an increasing number of interpretation
studies is being published, addressing various key aspects: the extension of
mixed cores, the structure of near surface convective zones, magnetic activity,
mass loss, ... Definitive conclusions will require cross-comparison of results
on a larger ground (still being built), but it is already possible at the time
of this Second CoRoT Symposium, to show how the various existing results take
place in a general framework and contribute to complete our initial scientific
objectives. A few results already reveal the potential interest in considering
stars and planets globally, as it is stressed in several talks at this
symposium. It is also appealing to consider the fast progress in the domain of
Red Giants and see how they illustrate the promising potential of space
photometry beyond the field of stellar physics, in connex fields like Galactic
dynamics and evolution.
