raouafi-2025-switchback-coronal-jet-precursors
Runtime-neutral paper-skill. Layered: (1) scientific invariants, (2) executable protocol against abstract capabilities, (3) adapter notes (optional examples only), (4) research-generation affordances.
Trigger
Reach for this skill when testing whether coronal jets are precursors of PSP-observed magnetic switchbacks by back-mapping switchback footpoints via PFSS to candidate jet sites.
Layer 1 — Scientific invariant
Paper identity
- Title: Tracing Magnetic Switchbacks to Their Source: An Assessment of Solar Coronal Jets as Switchback Precursors
- First author: TODO_verify
- Authors: TODO_verify
- Year: 2025
- arXiv: 2501.12340 (posted 2025-01-21)
- Journal: TODO_verify_with_full_text
- DOI: TODO_verify_with_full_text
Claim (narrow form)
A statistically significant subset of PSP switchback patches back-maps via PFSS to coronal-hole jet locations within the paper's spatial-temporal tolerance, supporting (but not uniquely proving) jet-driven switchback formation.
Method assumptions
- Switchback patches at PSP are correctly identified.
- PFSS + ballistic back-mapping is accurate enough at the relevant scales.
- Coronal-hole jet catalog is complete in the relevant window.
Data assumptions
- PSP FIELDS + SWEAP for switchback identification.
- AIA EUV for jet catalog.
- Synoptic Br for PFSS.
Failure modes (skill memory)
- Switchback-patch boundaries depend on deflection threshold.
- Back-mapping uncertainty broadens at low vsw.
- Jet catalog completeness varies by AIA channel.
Figure / numerical targets
- Switchback footpoint overlay on EUV jet sites.
- Time-distance plot of switchback occurrence vs jet activity.
- Statistical significance test panel.
Claim boundary
In scope. The paper's PSP encounter window and jet catalog.
Out of scope — do NOT generalize:
- Do NOT claim jets cause all switchbacks.
- Do NOT cite the precursor association without re-checking under alternate switchback definitions.
Layer 2 — Executable protocol (capability-typed)
Required capabilities (abstract)
| Capability | Purpose | Notes |
|---|
psp.fields_b() | PSP MAG | burst+survey |
sw.identify_switchback_patch() | switchback patches | threshold knob |
imagery.fetch_aia() | EUV for jets | |
jet.detect_coronal_hole() | jet catalog | automated/manual |
pfss.solve() | footpoint mapping | |
backmap.ballistic() | ballistic backmap | |
Procedure
- Identify switchback patches at PSP.
- Back-map each patch to source surface (ballistic + PFSS).
- Build jet catalog from EUV imagery.
- Co-locate footpoints and jets; assess significance.
Validation target
Recover the paper's jet–switchback association significance.
Layer 3 — Adapter / runtime notes (optional examples)
- sunkit-magex.pfss + ballistic backmap example in .library/custom/pfss-tracing/.
Layer 4 — Research-generation affordances
- Tension with [[bale-2021-solar-source-switchbacks-magnetic-funnels]]: funnel-driven vs jet-driven switchback origins; the footpoint atlas separates them.
- Generative hypothesis: re-running with [[deforest-2024-flux-fluxon-coronal-modeling]]'s fluxon-based connectivity should reveal jet associations missed by gridded PFSS.
