The exoplanet revolution that began two decades ago has drastically changed our understanding of the formation of extra-solar systems. Today we face an extreme diversity and complexity of these systems that can only be understood through the intimate link that exists between the planets and their host stars. The understanding and the detection of the exoplanets must be made more and more in close collaboration between stellar and planetary physicists. The purpose of the school is to provide participants interested in the field of exoplanetology an overview of the latest knowledge of stellar physics and will also give those in stellar physics a context to apply their work to an expanding field. An important place will be reserved  to promote exchanges with the teachers.

The SOC : L. Bigot (chair, OCA), J. Bouvier (co-chair, IPAG),  A. Chiavassa (OCA), Y. Lebreton (LESIA), A. Lèbre (LUPM). 

The school is limited to 45 participants.
