The restless motion of extrasolar planets around their host stars is a key property to discover and study them in detail. About 5800 exoplanets have been confirmed through 2024 and missions like Kepler, K2, TESS, and in the near future PLATO, are discovering thousands of new planet candidates. With the wealth of high-sensitivity data from JWST, and the ELT on the horizon, our understanding of these exoplanets and their atmospheres is rapidly evolving. This session aims at bringing the exoplanet community in Germany and its neighboring countries together to present recent advances in the techniques and results of exoplanets detection and characterization. The topics of this session include, but are not limited to,

- exoplanet observations / discoveries
- interpretation of exoplanet surveys
- observations and modeling of exoplanetary atmospheres
- exoplanet-exoplanet interaction and transit timing variations
- orbital evolution from tides, spin-orbit effects, stellar binaries etc.
- exoplanet characterization (composition, internal structure)
- formation and evolution of exoplanets.

The connection of these topics with ongoing/upcoming ground-based monitoring campaigns and space missions will be particularly relevant.
