The Non-Eruptive Reconfiguration of a Quiescent Filament After a Nearby Active Region Emergence
James McKevitt, Louise Harra, Gherardo Valori +13
The unpredictability of solar filament eruptions presents major challenges for forecasting space weather, as such eruptions frequently drive coronal mass ejections (CMEs) that impa…

Evolution of solar and stellar coronal abundances due to magnetic activity
David H. Brooks, Deborah Baker, David M. Long. Paola Testa +1
We discuss the evolution of solar coronal element abundances over an active region lifetime. Magneto-convection drives the complexity of magnetic fields that emerge above the photo…

Thread Separation and Expansion Observed in Multi-Stranded Solar Coronal Loops
David H. Brooks, Harry P. Warren
The theoretical expectation that coronal loops should expand with height contrasts with observations that typically show constant cross-sections. We investigate the idea that this…
