How Does the Critical Torus Instability Height Vary with the Solar Cycle?

open access: yesThe Astrophysical Journal
The ideal magnetohydrodynamic torus instability can drive the eruption of coronal mass ejections. The critical threshold of magnetic field strength decay for the onset of the torus instability occurs at different heights in different solar active regions,
