nadol-2026-magnetic-separator-reconnection-flare-ribbons
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 interpreting complex flare-ribbon morphology via PFSS+NLFFF-identified magnetic separators and quantifying separator-reconnection flux.
Layer 1 — Scientific invariant
Paper identity
- Title: The Role of Reconnection at Magnetic Separators in Complex Solar Flare Ribbons
- First author: TODO_verify
- Authors: TODO_verify
- Year: 2026
- arXiv: 2603.23789 (posted 2026-03-24)
- Journal: TODO_verify_with_full_text
- DOI: TODO_verify_with_full_text
Claim (narrow form)
Complex flare ribbons trace PFSS+NLFFF magnetic separators for a non-trivial fraction of events; separator-reconnection flux estimated from ribbon morphology agrees with NLFFF-predicted separator energy within tolerance.
Method assumptions
- Separator extraction is robust at the chosen grid.
- Ribbon morphology can be mapped to separator footprints.
Data assumptions
- AIA 1600/304 Å ribbon imagery.
- HMI vector magnetograms.
- Synoptic Br for PFSS background.
Failure modes (skill memory)
- Ribbon mask quality depends on threshold.
- Separator extraction at AR-edge boundaries is noisy.
Figure / numerical targets
- Ribbon overlay on PFSS+NLFFF separators.
- Separator-reconnection-flux vs ribbon-flux scatter.
Claim boundary
In scope. Studied complex flare-ribbon events.
Out of scope — do NOT generalize:
- Do NOT generalize to simple two-ribbon flares without re-extracting separators.
- Do NOT cite the separator-flux match independent of NLFFF boundary preparation.
Layer 2 — Executable protocol (capability-typed)
Required capabilities (abstract)
| Capability | Purpose | Notes |
|---|
imagery.fetch_aia() | AIA 1600/304 | |
magnetogram.fetch_hmi_vector() | HMI vector | |
pfss.solve() | background | |
nlfff.solve() | AR volume | |
topology.extract_separators() | separators | |
flux.separator_reconnection() | separator flux estimate | |
Procedure
- Identify ribbon masks.
- Solve PFSS+NLFFF.
- Extract separators; project on photosphere.
- Compute separator-reconnection flux.
- Compare to ribbon-flux estimate.
Validation target
Reproduce the separator-flux–ribbon-flux scatter.
Layer 3 — Adapter / runtime notes (optional examples)
- sunkit-magex.pfss; NLFFF code is paper-specific.
Layer 4 — Research-generation affordances
- Compose with [[mackay-2026-tracking-magnetic-topology-change-corona]] — track separator continuity across ribbon evolution.
- Generative hypothesis: ribbon→separator alignment quality predicts dimming morphology ([[razquin-2026-coronal-dimming-magnetic-flux-may2024]]).
