The scope of this workshop is to gather a limited number of expert scientists to discuss the challenges and lessons learned from orbital and dynamical studies of exoplanets with different techniques (radial velocity, transits, imaging, astrometry) and points of high importance for the optimal exploitation of new data (TESS, Gaia DR3+, ESPRESSO, CHEOPS,...) and upcoming facilities (JWST, PLATO, WFIRST/Roman Space Telescope, ELTs, ARIEL,...) for further studies.

There will be review talks, contributed talks, and posters. Review talks will cover the general theory of orbital fitting and dynamics of exoplanets and the various data used for such analyses so that contributed talks and posters can focus on the applications to exoplanetary systems including the presentation of methods and packages. We plan to publish the outcome of the discussions as a refereed paper for PASP.
