Planetary Science Seminar: The ongoing mystery of Jupiter's interior structure

The Juno spacecraft has been orbiting Jupiter since 2016 to inform us about Jupiter's formation, interior structure including the prominent atmospheric winds, and the early solar system. From the rich set of observational parameters, increasing evidence is emerging that the interior is stably stratified rather than convective, like the more massive Brown Dwarfs or our low-mass Earth are. However, the incredible accuracy of the observational data is giving modelers a hard time to find successful models with predictive power at all. After a short journey through some highlights, I will discuss Jupiter in regard of the still surprising uncertainty in the behavior of warm dense H/He. This talk is supposed to advertise continuing efforts to study their miscibility and equation of state. I will also propose a revolutionized view of the *revolutionary* insight from Juno of a dilute core in Jupiter by suggesting the gravity field is shaped by the distribution of helium. Finally, we will touch on the heavy noble gases Ne and Ar as tracers of interior structure.
