Jupiter’s infrared aurora and ionosphere (AST/2020/STA2)


Project Description

With the arrival of NASA's Juno mission at Jupiter, with magnetic measurements and ionospheric soundings by the spacecraft, our understanding of these aurora is changing dramatically. Instrumentation on the spacecraft itself is highly limited, and in the past, our understanding of how these aurora are formed and what magnetospheric processes drive them have both been greatly enhanced by our ground-based observations of the planet.

We have recently observed Jupiter's aurora in the infrared using a range of different world-class telescopes, including Keck, VLT and IRTF, in many cases at the same time as the spacecraft flew over the auroral region taking in-situ measurements. Our observations have also measured the equatorial regions, revealing for the first time a wide range of ionospheric features that can be directly compared with Juno magnetometer measurements.

This project gives the student an opportunity to work with observational data taken at these world-class telescope, analysing the data to produce fundamental new understanding of the process that drive the aurora and equatorial ionosphere of Jupiter. If data is available, the project could also include analysis of Juno JIRAM measurements of these regions from in-situ around the planet. An important additional component of the project work will include helping to observe infrared emission from the Gas Giants, either using remote observations, or on-site at the telescope - past students have visited the Mauna Kea Observatories in Hawaii to do this.
