Modeling Time-Variable Elemental Abundances in Coronal Loop Simulations
Jeffrey W. Reep, John Unverferth, Will T. Barnes +1
Numerous recent X-ray observations of coronal loops in both active regions (ARs) and solar flares have shown clearly that elemental abundances vary with time. Over the course of a…

Mass Flows in Expanding Coronal Loops
Jeffrey W. Reep, Roger B. Scott, Sherry Chhabra +2
An expansion of cross-sectional area directly impacts the mass flow along a coronal loop, and significantly alters the radiative and hydrodynamic evolution of that loop as a result…

Spectroscopic Observations of Coronal Rain Formation and Evolution following an X2 Solar Flare
David H. Brooks, Jeffrey W. Reep, Ignacio Ugarte-Urra +2
A significant impediment to solving the coronal heating problem is that we currently only observe active region (AR) loops in their cooling phase. Previous studies showed that the…
