Planets: Exoplanets - Space : Infrared Interferometry.

Scientific paper

The DARWIN mission aims at directly detecting telluric extrasolar planets in the solar neighborhood and performing a spectral analysis of their potential atmosphere to determine their composition and identify tracers of biological activity. The concept under study is a space infrared interferometric observatory made of 3 to 6 telescopes combined in a so-called "nulling" mode to cancel the light of the star and thus reduce the contrast between the star itself and the planet to detect. In this paper, we present the science cases of such an observatory, the concept of the beam combining instrument, and the associated key technologies. Finally, we consider what a post-DARWIN could be.
