Interactive use of computational models and experimental data in planetary science

Convener: Maxim Khodachenko
Co-Conveners: Vincent Génot, Esa Kallio

Acquisition of experimental data by space mission measurements and interpretation of these data on the basis of developed theoretical concepts and models are two major mutually connected aspects of the modern space research. Numerical modelling, as a way to reproduce complex natural phenomena and to understand them by computational simulation, plays here an important role. By this, the observational data on one hand are considered as a verification test for validity checking of existing models, on another hand they appear a driver for further improvement of existing models and development of new ones. At the same time, the scientific potentials of the combined use of experimental data and numerical models in their mutually complimentary way are still not realized. Creation of an integrated IT framework where numerical models are interconnected to the experimental data and used in combination with the last for simulation of space phenomena and interpretation of measurements, provided by space missions is an actual task. Recently started EU FP7 project IMPEx (Integrated Medium for Planetary Exploration) is aimed at making progress on that way. The splinter session is going to serve the establishment and stimulation of cooperation between observers, numerical modellers, as well as data resource developers and providers. Representatives from these fields, as well as all interested in the subject, are kindly invited to take part in the session which will be organized in the form of an open discussion and opinions exchange between participants.

Exoplanetary magnetic fields and stellar-planetary magnetic interactions: Modelling, detection, characterization

Convener: Maxim Khodachenko
Co-Convener: J.-M. Grießmeier

Session Details:

Constantly growing amount of discovered exoplanets and accumulation of data regarding their physical and orbital characteristics provides the material for study of general principles and major trends of planetary evolution. A number of actual questions regarding the evolutionary paths of exoplanetary systems and influencing them key factors is nowadays under continuous tackling. Among these questions a prominent position belongs to the problem of stellar - planetary interactions, including consideration of influences of stellar radiation and plasma flows on planetary environments and evolution of planets. Magnetic fields, those connected
with the planetary intrinsic magnetic dipole, as well as the magnetic fields associated with the electric current systems induced in the planetary close surroundings, play here an important role. Being focused on the specifics of exoplanetary magnetism, the session due to the generality of its subject welcomes participants from the whole circle of stellar and exoplanetary physics, including such topics like stellar activity, observation and characterization of planetary systems,
stellar-planetary relations, planetary evolution, dedicated computational modelling and data analysis. Special emphasis of the session is put on the transfer of experiences gained during the study of magnetospheres and magnetism of the solar system planets to the new field of exoplanets, taking into account the specifics of orbital location of exoplanets, stellar activity etc. Implementation of the theoretical/computational predictions to the observational and detection techniques appears as another key topic of the envisaged discussions during the session.
