Arago will allow us to obtain a full picture of the 3D dynamical environment of stars and planets, their interactions, and explore the conditions for the emergence of life on exoplanets. Arago is a candidate for ESA M5. It is prepared by a consortium of ~250 scientists in 21 countries.
Benchmark of spectrum codes
We are preparing for a benchmark test of spectrum codes from the planetary and the stellar community which will be applied to spectral observations of extrasolar planets as planed by future space missions. These test cases are stimulated by discussions in the EChO WG1.
