Searching for low-mass stars with magnetically-induced hyper-inflated radii
D. J. Mullan, J. MacDonald
Precise empirical estimates of stellar radii have revealed that the radii of certain low-mass stars are inflated relative to stellar structure predictions: the largest inflations o…

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…

The Rotation-Activity Correlations in K and M dwarfs. I. Stellar parameters, compilations of and for a large sample of late-K and M dwarfs
E. R. Houdebine, D. J. Mullan, F. Paletou +1
Reliable determination of Rotation-Activity Correlation (RAC's) depends on precise measurements of the following stellar parameters: , parallax, radius, metallicity, and r…
