Notes
Below are some rough notes from the discussion that followed this session at SHINE 2018. For more specific information, see the slides from both invited and contributed talks.
Scene-setting Talk 1
- lots of structure when you zoom into ARs
- primary tools for loop studies---EUV and X-Ray
- nanoflares---impulsive heating, agnostic to underlying cause
- short-lived brightenings in moss, blue shifts signature of nanoflares
- nanoflares popular, but mechanism highly-debated
- persistent blue shifts from active regions; occur where intensity (density) is lowest
- outflows due to interchange reconnection between closed loops and open fieldlines
- enhenaced low FIP elements in AR outflows
- two-step reconnection process
- non-Maxwellian diagnostics
Scene-setting Talk 2
- sources?
- open field
- dipolar streamers
- pseudostreamers
- transients
- Heavy ions
- ion composition determined within 4 to 5 solar radii
- determined by loop properties and release mechansims; no evolution during propagation
- elemental abundances determined within 1 to 2 solar radii
- Test particles in the flow, do not control the flow
- Fastest wind has lowest charge state
- Slow wind broader range of Fe to O, but higher charge state
- Open magnetic fields linking back down to ARs---how?
- High time resolution measurements may help to disentangle sources of multi-temperature plasma
- Ionization state may be a useful marker for mapping between wind and locations on the Sun
- How does photoionization affect this?
- From remote sensing enhancements, can we correlate with enhancements in in-situ data?
- Time-dependence important, but hard to resolve with current instrumentation
Additional Questions
- Can we use loop models to simulate these processes?
- How can we connect them to wind models?
- How to produce wind observables?
- What constraints can IRIS/EIS provide? [follow-up from Vanessa's talk]
- Deviations from Maxwellians? Are there correlated between ARs and wind?
- But a lot happens (kinetic-wise) between the Sun and 1 AU... [Lepri and Viall]
- How consistent are periodicities in the wind?
- Correlations between outflows and type III radio bursts? Need statistics... [Bin Chen]
