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 relating an AR blowout-jet trigger to a PFSS+NLFFF magnetic-topology configuration (fan-spine, nulls, QSLs).
Layer 1 — Scientific invariant
Paper identity
- Title: Investigation of Magnetic Topology and Triggering Mechanisms of a C-Class Flare and Active-Region Blowout Jet
- First author: A. Prasad
- Authors: A. Prasad, TODO_verify
- Year: 2026
- arXiv: 2602.01742 (posted 2026-02-02)
- Journal: TODO_verify_with_full_text
- DOI: TODO_verify_with_full_text
Claim (narrow form)
The studied blowout-jet onset is triggered at a fan-spine null identified by PFSS+NLFFF, with QSLs aligning with the observed jet base — a topology that recurs in a paper-identified subclass of blowout jets.
Method assumptions
- Fan-spine null is robust to small NLFFF perturbations.
- QSL extraction is reproducible.
Data assumptions
- HMI vector + LoS Br.
- AIA EUV time series.
- Synoptic Br for PFSS background.
Failure modes (skill memory)
- QSL extraction depends on Q-factor threshold.
- Null identity drifts with NLFFF boundary prep.
Figure / numerical targets
- Fan-spine topology with null overlay.
- QSL footprint at jet base.
Claim boundary
In scope. The studied event.
Out of scope — do NOT generalize:
- Do NOT generalize the fan-spine trigger to all blowout jets.
- Do NOT cite QSL alignment independent of Q-threshold.
Layer 2 — Executable protocol (capability-typed)
Required capabilities (abstract)
| Capability | Purpose | Notes |
|---|
magnetogram.fetch_hmi_vector() | HMI vector | |
imagery.fetch_aia() | AIA EUV | |
pfss.solve() | background | |
nlfff.solve() | AR volume | |
topology.identify_fan_spine_null() | fan-spine null | |
topology.qsl_q_factor() | QSLs | Q threshold |
Procedure
- Solve PFSS+NLFFF.
- Identify fan-spine null near AR core.
- Extract QSLs; project to photosphere.
- Overlay AIA jet base.
Validation target
Match QSL footprint to AIA jet base.
Layer 3 — Adapter / runtime notes (optional examples)
- sunkit-magex.pfss; NLFFF + Q-factor codes paper-specific.
Layer 4 — Research-generation affordances
- Compose with [[raouafi-2025-switchback-coronal-jet-precursors]] — blowout-jet topologies as switchback precursors.
- Generative hypothesis: fan-spine subclass should correlate with [[nadol-2026-magnetic-separator-reconnection-flare-ribbons]] complex ribbons.
