Hisaki Io Plasma Torus Workshop
Dates:
The workshop will run all of Wednesday, Thursday, Friday Jan 25, 26, 27th in the LASP Space Sciences building – SPSC. See map below.
Topics:
– Hisaki data handling – tutorial
– Spectrum diagnosis with 140″ slit
– Spectrum diagnosis with 140″ slit during volcanic activity
– What’s the hot electron temperature? 40 eV? 300 eV?
– What’s the hot electron fraction? Or do we need a kappa? Can we tell from the UV spectrum?
– Hot electron temperature deduced from light curve
– Are hot electrons convected in from the plasmasheet or are they produced locally in the torus?
– Are the torus electrons heated by the Io interaction?
– Overview of the volcanic activity in 2015
– Does the composition vary with Io’s volcanic activity?
– Parallel temperature of S+ during volcanic activity
– Is there a UV “ribbon”?
– Neutral oxygen during volcanic activity
– How the magnetosphere responds to the plasma mass loading from Io?
– Control of Io for the radial flow of torus plasmas
– Is the System III periodicity variable with radial distance? With time?
– System IV variation with space and time
– Ground based observation of neutral sodium in the Jovian magnetosphere
– Is there a relationship between variations in the torus and aurora?
– What’s the physical process?
– How do aurora and/or torus observations vary with the solar wind?
– What are the physical processes?
– Response of IPT to SW (Comparison with JUNO)
– How do models of the solar wind compare with in situ measurements by JADE?
Hisaki Data:
We are downloading all the Hisaki/Exceed data from Darts and will have them available to easily access from a storage disk. We urge everyone to bring their laptops and computer codes so that we can compare our different analysis programs.
Papers to read:
Here’s the bibliography page where we’ve been listing papers on the Io torus.
