Convex hulls of irregular solar pore boundaries allow reliable detection of sausage and kink wave modes while degrading higher fluting modes.

Claims

C1strongest claim

The fundamental sausage (m=1) and kink (m=2) mode is found to remain reliable, while higher-order fluting modes (m≥3) are strongly degraded by small-scale boundary irregularity. Sausage-like modes dominate the variance at all heights and exhibit a systematic upward shift in frequency, consistent with freely propagating compressive waves.

C2weakest assumption

That the convex hull derived from intensity minimum error thresholding accurately represents the effective magnetic flux domain for wave propagation analysis across the observed range of pore shapes.

C3one line summary

A convex hull method for irregular solar pore boundaries enables reliable identification of sausage and kink wave modes, showing sausage modes propagate upward while kink motions appear as forced responses to granular buffeting.
