How does the critical torus instability height vary with the solar cycle?
Alexander W. James, Lucie M. Green, Graham Barnes +2
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…

Searching for evidence of subchromospheric magnetic reconnection on the Sun
D. Baker, L. van Driel-Gesztelyi, A. W. James +13
Within the coronae of stars, abundances of those elements with low first ionization potential (FIP) often differ from their photospheric values. The coronae of the Sun and solar-ty…

Identifying plasma fractionation processes in the chromosphere using IRIS
David M. Long, Deborah Baker, Andy S. H. To +7
The composition of the solar corona differs from that of the photosphere, with the plasma thought to fractionate in the solar chromosphere according to the First Ionisation Potenti…
