The CoRoT is a pioneering mission for the space-based study of extra solar planets and asteroseismology. The First CoRoT Symposium held in Paris in February 2009 focused on the first scientific results from the mission. CoRoT has been delivering high precision photometric data since January 2007 and the first two years of CoRoT data are now public. These data have been analyzed by a broader community for science beyond the initial objectives of CoRoT.

The aim of this conference is to explore the synergy between exoplanets and asteroseismology. By bringing the planetary and stellar communities together this symposium seeks to give rise to new projects that will lead to advances in the integral study of planetary systems and their host stars.

In particular, the following topics will be presented:

• The outcome from transit modeling from space-based data
• The composition of planets, from super-Earths to giant planets and how they compare to the solar system
• The orbital evolution of extrasolar planets: constraints from CoRoT to the formation and migration scenarios
• Multi-planet systems in transit and variation of transit ephemeris: implication on their dynamics
• Reflected light of close-in planets, phase modulation and secondaries
• Satellites of transiting planets, searches for and theoretical constraints
• Oscillations in the HR diagram, from solar like stars to hot stars, giants and subdwarfs
• Stellar cores and the age scale
• Mixing processes as revealed by seismology
• Convective transport in stellar envelopes
• Seismology as a tool for statistical stellar physics and galactic structure
• Activity and rotation
• The variety of ecclipsing binary systems
• Prospects for future missions
