Saturn’s rings provide astronomers with local analogues for the remote proto-planetary disks surrounding
stars and forming the nurseries of extra-solar planets.
In July 2004, Cassini started remote and in-situ investigations of the Saturnian rings system.
These unique observations revealed in real time the diversity and dynamics of a complex
and evolving system, addressing to a large extent questions relevant to the solar and
stellar systems’ origins. In the recent years, ground- and space-based astronomical
observations over a wide range of wavelengths (e.g., high-precision spectroscopy in the
optical and near-IR, HST, Spitzer, …) have also been providing us with new emerging clues
about proto-planetary disk evolution and planet formation, yet to be detailed over the
next several years (e.g., Corot, ALMA, Herschel, JWST, …).
The similarities in term of the physical and dynamical processes operating in
these planetary and astrophysical systems - via collisions, conservation of
angular momentum, energy transfer between ring/debris disk particles and
moons/embryonic planets, as well as the interplay of gravity, radiation and
electromagnetic forces – are striking and led us to anticipate possible
refinement of current models/simulations of planetary and ring/satellite
systems formation by taking all observational constraints into account.
This workshop-like session is intended to bring together observers and
modellers in the planetary and astrophysical communities in order to
provide a stimulating environment for exchanging ideas and current
views on these issues.
