Empirical measures of the largest amounts of magnetically-induced radius inflation in low-mass stars
D. J. Mullan, J. MacDonald
Access to precise empirical estimates of stellar radii in recent decades has revealed that the radii of certain low-mass stars are inflated relative to stellar structure prediction…
The Role of the Convective Kissing Instability in Cataclysmic Variable Evolution
Conor M. Larsen, James MacDonald
The convective kissing instability (CKI) is postulated to occur in low mass stars around the fully convective transition. Non-equilibrium He burning leads to the merging of c…
A plasmoid-model for mass loss from stars on the upper red giant branch: The mass loss rate is controlled by the number of density scale heights in the convection zone
J. MacDonald, D. J. Mullan
Recent asteroseismic determinations of ΔM, the integrated mass loss on the red giant branch (RGB), for fields stars show a trend of ΔM decreasing as metallicity increases. This tre…
Early Post Asymptotic Giant Branch Instability: Does it Affect White Dwarf Hydrogen Envelope Mass?
James MacDonald
Although most white dwarf stars have hydrogen-dominated atmospheres, a significant fraction have atmospheres in which hydrogen is spectroscopically absent, with the fraction of hyd…
The Effects of Magneto-Convection on Short Period Cataclysmic Variables
Conor M. Larsen, James MacDonald
Many of the current problems related to the evolution of cataclysmic variables revolve around the magnetic nature of the main sequence secondary. It is known that magnetic fields a…
