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…

An elemental abundance diagnostic for coordinated Solar Orbiter/SPICE and Hinode/EIS observations
David H. Brooks, Harry P. Warren, Deborah Baker +2
Plasma composition measurements are a vital tool for the success of current and future solar missions, but density and temperature insensitive spectroscopic diagnostic ratios are s…
