Scientific Rationale:

The past few years have been scene to major developments in planetary astronomy. The successful ending of Cassini mission, the discovery of new planetary systems with Kepler/K2 telescope, and the unprecedented results obtained from Dawn and New Horizons have revolutionized our understanding of planetary systems and have opened new chapters in observational and theoretical research in solar system and exoplanetary astronomy. The IAU Division F (Planetary Systems & Astrobiology), in conjunction with the 30th General Assembly of the International Astronomical Union, is organizing a two-day workshop on recent discoveries and advances in planetary science. The purpose of this workshop is to bring together researchers from all fields of planetary astronomy to present their new findings in form of oral and poster presentations, and discuss the current state of research in our field. Some research topics have been listed below, however, the workshop is open to all fields in solar system and extrasolar planets.



  • Solar System
    • Observations (e.g., Planets IX, I1/2017 U1, small bodies)
    • Space Missions (Dawn, Cassini, Hayabusa 2, Osiris-Rex, New Horizons)
    • Formation, Dynamics, and Physical Evolution
    • Asteroid Deflection

  • Exoplanetary Systems
    • Observations (Ground-based, Kepler, K2, etc.,)
    • Theory (Formation, Dynamics, Migration, Multiple Star Systems)
    • Atmosphere
    • Habitability
    • Future Missions (e.g., TESS, PLATO)

Registration is now open and abstracts are accepted for oral and poster presentations. We encourage all planetary astronomers to submit abstracts. Participants in this workshop will receive admission to all scientific activities of the IAU General Assembly including the Focus Meeting 1 on asteroid families, IAU Symposium 345 on the origin of life and planetary  systems, and a training school in Astrobiology held on August 17-18, 2018 by the University of Vienna.
