lapenta-2026-magnetic-connectivity-time-dependent-corona
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 handling magnetic-connectivity evolution on day-to-hour timescales, where steady PFSS is insufficient and a time-dependent coronal model is required.
Layer 1 — Scientific invariant
Paper identity
- Title: Magnetic Connectivity in the Time-Dependent Corona and Heliosphere
- First author: TODO_verify
- Authors: TODO_verify
- Year: 2026
- arXiv: 2603.22440 (posted 2026-03-23)
- Journal: TODO_verify_with_full_text
- DOI: TODO_verify_with_full_text
Claim (narrow form)
A time-dependent coronal/heliospheric model produces connectivity sequences whose discontinuities (rapid footpoint jumps) coincide with reconnection events identified in EUV / in-situ — a behaviour invisible to single-CR PFSS.
Method assumptions
- Time-dependent model is converged on relevant sub-day cadence.
- Connectivity jumps are robust to small parameter perturbations.
Data assumptions
- High-cadence magnetogram driver (HMI 720s / vector).
- Reference PFSS snapshots for comparison.
Failure modes (skill memory)
- Driver-cadence vs internal timestep mismatch.
- PFSS snapshots may falsely smooth real jumps.
Figure / numerical targets
- Footpoint-trajectory time series with jumps annotated.
- Connectivity discontinuity vs EUV reconnection event.
Claim boundary
In scope. The paper's window + time-dependent model.
Out of scope — do NOT generalize:
- Do NOT cite the discontinuity correspondence outside the validated event sample.
- Do NOT replace steady PFSS with the time-dependent model where convergence is not demonstrated.
Layer 2 — Executable protocol (capability-typed)
Required capabilities (abstract)
| Capability | Purpose | Notes |
|---|
magnetogram.fetch_high_cadence() | HMI 720s | |
coronal.time_dependent_solve() | time-dependent model | |
connectivity.trace_footpoint() | footpoint over time | |
imagery.fetch_aia() | reconnection-event imagery | |
pfss.solve() | steady-PFSS comparison | |
Procedure
- Drive time-dependent model with HMI 720s.
- Trace footpoint trajectories for observers of interest.
- Mark discontinuities; correlate with EUV reconnection events.
- Compare to steady-PFSS-snapshot footpoints.
Validation target
Reproduce the discontinuity–event correspondence.
Layer 3 — Adapter / runtime notes (optional examples)
- sunkit-magex.pfss for steady-PFSS reference; time-dependent code is paper-specific.
Layer 4 — Research-generation affordances
- Compose with [[mackay-2026-tracking-magnetic-topology-change-corona]] for a unified topology-change tracking framework.
- Generative hypothesis: discontinuities classified by amplitude predict switchback occurrence at PSP ([[raouafi-2025-switchback-coronal-jet-precursors]]).
