[IGPP Everyone] Space Physics seminar, EPSS Faculty Candidate - Fri. 4/1, 3:30 PM PST - The Shape of the Wind: Discovering Magnetic Topology Throughout the Heliosphere (P. Whittlesey, UCB SSL)

Mon Mar 28 11:26:54 PDT 2022

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 Shape of the Wind: Discovering Magnetic Topology Throughout the Heliosphere

Plasma and energy transfer throughout the solar system is constrained and influenced by the magnetic structures, whether they originate from the sun, planetary magnetospheres, or interactions at the interfaces between the two. Studying the shape of the heliosphere and the magnetospheres within is one path to constrain the energy flow and transfer on all scales. By examining the magnetic alignment of strahl, or magnetic-field aligned, low-energy electrons within the solar wind, we can identify whether regions of solar wind and magnetospheric plasma are connected to the sun, magnetospheres, or both simultaneously. This talk will cover how recently launched missions, such as Parker Solar Probe in the inner heliosphere, as well as missions currently in development, such as ESCAPADE bound for Mars, are leveraging critical electron measurements of magnetic topology to characterize the flow and transfer of energy from their sources on the sun to smaller scales via features such as solar wind turbulence and magnetic switchbacks. Via comparison with heliospheric magnetic field modeling, the Parker Solar Probe / SPAN-E electron experiment is making definitive connections between large scale structures, such as the heliospheric current sheet and sources of fast and slow wind, with photospherically observable regions on the sun such as coronal holes and acceleration regions. In the future, the ESCAPADE e-EESA instruments will be able to identify the extent to which the solar wind is eroding the Martian atmosphere via interactions with its hybrid magnetosphere. Additionally, the recently selected HelioSwarm mission will host an entirely student-designed low-energy electron instrument that will definitively determine when this mission is within the pristine solar wind in order to study solar wind turbulence. The ability of these three missions to operate together in tandem and also with others as a topological observatory will be discussed.
