Topics
1. Methods of exoplanets detection and characterization
2. Effects of the stellar activity on detectability Earth-type planets
3. Stellar activity, star-planet interaction and habitability of exolnanets
4. Numerical simulations of the stellar surface and interiors dynamics and interaction with atmosphere
5. Magnetic interaction in stellar chromospheres, coronae and winds, and effects on planetary atmospheres and exospheres
6. Current and future missions and instrumentation for the exoplanet detection
Rationale
Discovery of the first extrasolar planets around pulsar PSR1257 + 12 and 51 Pegasi gave a start to development of observational and data analysis techniques, as well as to theoretical studies, to detect and characterize new planetary systems. Among the thousands of discovered exoplanets only few of them have masses similar to the Earth. Despite the intensive search for exoplanets by a wide range of methods from the ground and space the detection and characterization of low-mass planets (exo-Earths) with orbits located in the habitable zone is very challenging from the point of view of both instrumentation and analysis of observations that make critical characterize dynamics of a parent stars (“stellar jitter”) and properties of stellar activity. Understanding processes associated with stellar turbulent dynamics and star-planet interaction will shed light on properties of orbiting planets and their environment. At the present time, the fast growing computational capabilities allow us to generate 3D time-dependent simulations of stellar radiative magnetoconvection that are capable of reproducing the surface turbulent dynamics with a high degree of realism. In addition, state-of-art MHD simulations of planet interaction with stellar winds reveal effects on planetary atmospheres and magnetospheres. This Symposium will bring together observers, theoreticians, and modelers from different fields that will allow intense exchange experience and emerge new ideas.
