The study of planetary systems around other stars is a rapidly evolving field of research, with the long term objective to improve our understanding about the distribution of life in the
Universe and how it may have arisen on Earth.

Planetary systems are composed of one (or several) stars orbited at various distances by planets of different sizes and masses. The study of planetary systems must be considered as a whole and the evolution of planets cannot be studied separately from that of their host stars. Moreover the precise characterization of exoplanets requires a good knowledge of the characteristics of their central stars. This is why the areas of exoplanet investigation and stellar evolution are intimately linked.

Today, one decade after the discovery of the first giant exoplanet, we are entering
a new era with the recent launch of CoRoT in December 2006. For the first time, we have a tool for detecting efficiently telluric planets via their transits in front of their host stars, as well as for measuring very accurately the characteristics of stars including their radius, mass and age, as well as their internal structure and rotation, via asteroseismology. This tool is the ultra-high precision space-based photometric monitoring provided by CoRoT. Beyond CoRoT, future high precision photometry space missions, such as Kepler and PLATO, will permit seismic investigations of the host stars of transiting exoplanets, thus providing us with a full characterization of exoplanetary systems and tools to study their evolution in detail.

The objective of the school is to introduce the students to the fields of stellar evolution and exoplanet science. The school also covers the techniques of asteroseismology, planetary transit detection, and more generally space-based ultra-high precision photometric monitoring.

The school will be organized around general lectures, complemented by practical applications. The students will be able to run themselves numerical models and software in order to get acquainted with CoRoT data reduction and analysis.
