Colloquium title: Early release science observations of the Jovian System as a demonstration of JWST’s capabilities for Solar System science
Speakers: Imke de Pater (University of California, Berkeley & TU Delft) and Stephanie Cazaux (TU Delft)
Early Release Science data of the Jovian system (#1373) have been taken in July-August, and in Nov-Dec. These observations explore the planet’s atmosphere, its major and minor satellites and faint ring system. We will discuss the scientific rationale for and preliminary results of our observations.
• Jupiter has been observed for centuries and has been visited by several spacecraft. What secrets can JWST still reveal?
• Ganymede, the largest satellite in our Solar System, is composed of a molten core, a silicate mantle, and complex crust overlying a liquid water layer. Most intriguing, it has an intrinsic magnetic field. What can we learn from JWST about Ganymede’s crust and atmosphere?
• Io is the most volcanically-active body in our Solar System. What can JWST reveal us about Io’s surface and the way volcanoes may affect its atmosphere?
• The fine dust particles of the Jovian ring have a limited lifetime – perhaps years – due to solar radiation pressure and electromagnetic forces, and hence require a continuous supply of dust. What can JWST tell us about the rings and small moons?
