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…
K2 Ultracool Dwarfs Survey. IV. Monster flares observed on the young brown dwarf CFHT-BD-Tau 4
Rishi R. Paudel, John E. Gizis, D. J. Mullan +4
We present photometric measurements of two superflares observed on a very young brown dwarf CFHT-BD-Tau 4, observed during Campaign 13 of the \textit{Kepler K2} mission. The strong…
The Magnetic Binary GJ 65: A Test of Magnetic Diffusivity Effects
James MacDonald, D. J. Mullan, Sergio Dieterich
GJ 65 is a M dwarf binary system consisting of the two flare stars BL Cet (GJ 65A) and UV Cet (GJ 65B). Two teams of investigators have recently reported total magnetic fluxes corr…
Magnetic modeling of inflated low-mass stars using interior fields no larger than ~10 kilogauss
James MacDonald, D. J. Mullan
We have previously reported on models of low-mass stars in which the presence of inflated radii is ascribed to magnetic fields which impede the onset of convection (e.g. MacDonald…
LSPM J1314: An oversized magnetic star with constraints on the radio emission mechanism
James MacDonald, Dermott Mullan
LSPM J1314+1320 (=NLTT 33370) is a binary star system consisting of two nearly identical pre-main sequence stars of spectral type M7. The system is remarkable among ultracool dwarf…
The Age of the KIC 7177553 System
James MacDonald, D. J. Mullan
KIC 7177553 is a quadruple system containing two binaries of orbital periods 16.5 and 18 d. All components have comparable masses and are slowly rotating, non-evolved stars of spec…
