Auroral radiations have been detected from all explored magnetized planets of the solar system, where their emission is the result of a complex interaction between the sun, the solar wind, the magnetosphere, the ionosphere, as well as moons and rings. Auroral processes cover a wide range of wavelengths (from radio to X-rays) and generation mechanisms, that form a valuable diagnosis to probe remotely space plasmas, magnetospheric processes and their dynamics.

This session will be organized as:
- a workshop with invited presentations (only), that aims to review our current knowledge on known planetary aurorae by a multi-spectral comparative approach, and to address the fundamental questions of the dissipation of the energy transferred to auroral regions and the nature of the informations carried by radiated electromagnetic waves on associated magnetospheres and plasmas. The number of oral presentations will be limited to favor ample discussions.
- a poster session, where recent results obtained from the large set of observations provided by numerous spatial missions (Cassini, Galileo, HST...) and ground-based observatories (IR and radio telescopes) as well as theoretical developments are welcome. We also encourage contributions regarding future prospects in the frame of next missions to Jupiter (JUNO, EJSM), Mercury (Bepi-Colombo) and ongoing projects to Uranus, Neptune and the Earth. Posters will be shortly introduced at the end of the oral workshop.
