Second announcement

With the discovery of more than 1000 exo-planetary systems, the diversity of known star(s)-planet(s) systems and their configurations is wider and wider. The selection as Cosmic Vision M3 mission of the Plato satellite encourages the scientific community to organize itself to make the most useful use of the upcoming data, with the Corot and Kepler satellites having laid the basis of such an effort. In order to understand the multiplicity of observed configurations, we need to develop state-of-the-art theoretical and numerical models, which take into account simultaneously magnetic, tides and radiation interactions between the host star(s) and their surrounding planet(s) as well as their internal and structural evolution.
Interactions between the star-planet system and its interstellar environment at various phases of star evolution will also be discussed. Likewise defining with more accuracy what could be considered as the habitable zones of stars of various spectral type and the possibility to even have super-habitable worlds is timely.
This is the main goal of the Star-Planet Interactions and the Habitable Zone Workshop.
The workshop will focus on the latest developments obtained with high performance numerical simulations and on the modelling of the underlying physical processes to improve our knowledge and understanding of star-planet systems as well as their direct comparison with ground-based and space-born observations. The workshop will gather known experts from all over the world in a format favouring exchange and cross-fertilization by giving ample of time to discussion. The workshop will be organized 
following 4 sessions, one devoted to Tidal effects, one on MHD interactions, one on the evolution of stars and planets (atmosphere, rotation, structure) and the fourth one on the first attempts to couple these processes together. All sessions will discuss the impacts of these various effects/physical processes on habitability and on the condition of the emergence of life.
4 key-notes lecturers have agreed to open a session each day:
Day 1 on Tides and Habitability: Prof. Jacques Laskar
Day 2 on Magnetic Interaction and Habitability: Dr. Aline Vidotto
Day 3 on Evolution and Habitability: Prof. Gordon Ogilvie
Day 4 on Coupling all effects and Habitaiblity: Prof Nuccio Lanza

4-day workshop on the third week of November 2014 (18th to 21st) in Saclay, near Paris, France.

Acces: Bat 713- Salle Galilée in CEA-Saclay - Orme des Merisiers by RER B line (south bound to Saint Rémy les Chevreuses)  by stopping at  station “Le Guichet” and then taking a Bus up and stop at the bus stop: Orme des Merisiers - St Aubin (near synchotron Soleil). Then walk through the entrance with red brick walls and go in the direction of Building 713 (near 709 and 703) one of the first building on your left as you walk. In the evening, take the CEA shuttle from l'Ormes des merisiers (Building 703) to the le Guichet station to take RER B to Paris.

For those colleagues coming from outside the Paris area and from abroad we
have secured some funding to cover part of your expences. Deadline for requesting
a support is 1st of October.

No registrations fees and free lunches and coffee breaks will be provided.



To help you in your search we have an agreement for a discount CEA rate with some Hotels by using codename 

“CEA” or “SPI Workshop” or “Conference in Astrophysics”.
