ESO Workshop: A revolution in stellar physics with Gaia and large surveys

The era of Gaia-enabled revolutions in almost all areas of astrophysics has started. In particular, and crucially, Gaia exquisite astrometry and photometry combined with data of other large stellar surveys, from the ground and from space, are going to allow major progress in our understanding of stellar physics.

Stellar evolution is successful in describing the general aspects of the life of stars, nevertheless, many physical processes remain poorly understood. A correct and detailed description of stellar evolution has a fundamental impact on the comprehension of the formation of planetary systems and stars, and thus also on both Galactic and extra-galactic science.

The workshop will focus on discussions about the advances in our understanding of stellar physical processes made possible by combining the astrometry and photometry of Gaia with data of other large photometric, spectroscopic, and asteroseismic stellar surveys. Asteroseismology, in particular, has been essential to allow access to information coming from the interior of stars. These combined data will permit detailed studies of stellar physics to a level that is unprecedented in the history of stellar astrophysics.

Moreover, the large sample seen by Gaia will encompass many peculiar and rare objects including some undergoing rapid evolutionary effects, binaries undergoing all sorts of interactions, and pulsating stars of different types. This has a huge potential for new astrophysical discoveries and for uncovering new physical processes.

The goal of this workshop is to bring together the community that is working on fulfilling this promise of a revolution in stellar physics. The discussions will focus on the advances in stellar physics made possible from the combination of Gaia and large surveys. Attention will also be given to future missions and surveys that will either explore new types of data (polarimetry, different wavelength windows...), improve the precision of measurements, or enlarge samples and data coverage.
