[IGPP Everyone] TOMORROW: Space Physics seminar, EPSS Faculty Candidate - Fri. 2/25, 3:30 PM PST - The magnetic fields of giant planets in the era of Juno and Cassini (Hao Cao, Harvard U.)

[Emmanuel V. Masongsong]

The EPSS Department is conducting a faculty search for a new tenure-track position in Space Physics. The six finalists will present at our Space Physics Seminar series as shown at the bottom of this email, both in-person in the Slichter Hall 3853 Conference Room (3rd floor), and streamed via Zoom. The talks will also be recorded for those unable to attend. Light refreshments and an opportunity to meet the speaker informally will follow after the talk on the Franz Patio. 

Your feedback on the talks and other interactions is valuable to the Search Committee. Kindly submit your comments via the survey link which will be sent via email (please contact Helen Carter, hcarter at epss.ucla.edu, if you did not receive it and would like to contribute).

The magnetic fields of giant planets in the era of Juno and Cassini

We are at a golden age of giant planet exploration. The recently concluded Cassini mission to Saturn and the ongoing Juno mission at Jupiter have revealed many deep mysteries at the two gas giants: e.g., the cores of Jupiter and Saturn are diluted in the surrounding metallic hydrogen, their magnetic fields are significantly different to previous expectations, and the less energetic Saturn possesses much stronger and deeper winds compared to the more energetic Jupiter. These discoveries raise novel challenges and exciting possibilities. Magnetic field investigations have been crucial to these recent discoveries. 

In this presentation, I will highlight new features of the magnetic fields of Jupiter and Saturn from recent observations, including low-latitude field-aligned currents, ring-planet coupling currents, and spatial structure and time variations of the internal magnetic fields. I will then discuss implications and new questions raised for the interior, equatorial ionosphere, and innermost magnetosphere of the two gas giants. I will conclude this presentation with an outlook for the future exploration of gas and ice giant planets in the solar system, focusing on the essential role of magnetic field investigation.
