Ice Giant Systems Seminar Series: Dr. Kathy Mandt

Presenter: Dr. Kathy Mandt (JHU/APL)
Topic: Determining origin and evolution of Uranus with a single atmospheric probe
Abstract: Noble gas and nitrogen isotope ratio measurements from the giant planet atmospheres provide critical information on how the giant planets formed and migrated to their current positions. Comparing GPMS measurements to noble gas abundances and isotope ratios in Uranus are critical for understanding formation and evolution of ice giants compared to gas giants. We will discuss the importance of these measurements and whether Juno MWR results impact the GPMS noble gases and isotope ratios and the reliability of atmospheric probes, which are the only method for obtaining these critical observations.

Presenter: Dr. Adam Masters (Imperial College London)
Topic: Uranus' extreme and unusual magnetosphere
Abstract: Uranus is the first of the ice giant planets, orbiting the Sun ~19 times farther than the Earth. The solar wind continually bombards the planet, which is shielded by its internally generated magnetic field. This creates a large, dynamic, and invisible environment of magnetic fields and charged particles around Uranus that we refer to as the planetary magnetosphere. Understanding this complex system is a core element of understanding how energy flows through the entire planetary system, and Uranus' magnetosphere is both extreme and unusual in many respects. I will review what we currently know about Uranus' magnetosphere, which is largely based on a single spacecraft encounter by Voyager 2 in 1986. I will highlight what makes this magnetosphere so extreme and unusual, reviewing topics including the solar wind interaction, magnetospheric dynamics, the radiation belts, and the asymmetric field of Uranus itself. A future Uranus orbiter would provide a route to answering the many open questions in this field.
