Title of the postdoctoral project: Probing Saturn’s magnetosphere with auroral observations of Cassini and Hubble
The research project primarily aims at investigating the auroral processes and the dynamics at various timescales of Saturn’s magnetosphere, through the analysis of remote ultraviolet (UV) auroral observations recently acquired by the Cassini/UVIS spectro-imager and the Hubble Space Telescope (HST), complemented by in situ radio and plasma measurements of the Cassini spacecraft. The main objective of this project is to build and exploit a high level database of Cassini/UVIS auroral observations in the frame of the APIS service, and to take advantage of multi-platform measurements to disentangle and characterize the different components of kronian aurorae (e.g. energy budget, dynamics from short-term scales to solar/seasonal variations) and constrain the underlying acceleration processes. The Cassini ‘Grand Finale’, made of a series of high-inclination orbits, provided unprecedented vantage views on both the northern and southern UV aurorae together with unique in situ measurements along the auroral field lines. These observations were supported by coordinated HST instantaneous observations of the northern UV aurorae near solstice, precisely scheduled during the Cassini traversal of auroral field lines. Coincidentally, HST similarly observed the UV aurorae of other giant planets which offer an extended frame for comparative planetology.
