Mass loss on the red giant branch: plasmoid-driven winds above the RGB bump
D. J. Mullan, J. MacDonald
The onset of cool massive winds in evolved giants is correlated with an evolutionary feature on the red giant branch known as the bump. Also at the bump, shear instability in the s…

The umbral--penumbral boundary in sunspsots in the context of magneto-convection
D. J. Mullan, J. MacDonald
Jurcak et al (2018) have reported that, in a sample of more than 100 umbral cores in sunspots, the umbral-penumbral boundary (UPB) is characterized by a remarkably narrowly-defined…
