Mini-Seminar: Yannis Bennacer – Formation and Evolution of Jovian Satellites
Date: Friday April 10
Time: 10:15-10:45 (room is booked for the entire hour – we figured we would give people time to come up from Friday science, and for additional question time afterwards as needed)
Room: Larger 4th floor conference room (white chairs; 4.165) and webex dial in below
Speaker: Yannis Bennacer – PhD Student in Astrophysics at Laboratoire d’Astrophysique de Marseille
Title: Why Did the Galilean Moons Evolve So Differently? Insights from Accretion and Early Evolution
Abstract: The Galilean satellites of Jupiter exhibit striking contrasts, from the partially differentiated Callisto to the fully molten Ganymede, and from volatile-depleted Io to ice-rich Europa. Are these differences inherited from their formation environment, or do they result from divergent evolutionary pathways? Could similar accretion conditions produce radically different internal structures? Did Io and Europa form with their current rock-rich composition or could they have formed ice-rich and lost their volatiles? In this seminar, I will explore these open questions and discuss the key physical processes that may control the diversity of the Jovian satellite system.
