K2 Ultracool Dwarfs Survey. V. High superflare rates on rapidly rotating late-M dwarfs
Rishi R. Paudel, John E. Gizis, D. J. Mullan +4
We observed strong superflares (defined as flares with energy in excess of 10^33 erg) on three late-M dwarfs: 2MASS J08315742+2042213 (hereafter 2M0831+2042; M7 V), 2MASS J08371832…
Magnetic Fields on the Flare Star Trappist-1: Consequences for Radius Inflation and Planetary Habitability
D. J. Mullan, J. MacDonald, S. Dieterich +1
We construct evolutionary models of Trappist-1 in which magnetic fields impede the onset of convection according to a physics-based criterion. In the models that best fit all obser…
Photosynthesis on a planet orbiting an M dwarf: enhanced effectiveness during flares
D. J. Mullan, H. P. Bais
On planets near M dwarfs, photosynthesis (PS) will occur with an effectiveness which depends on the supply of visible photons with wavelengths between 400 and 700 nm. In this paper…
K2 Ultracool Dwarfs Survey. III. White Light Flares are Ubiquitous in M6-L0 Dwarfs
Rishi R. Paudel, John E. Gizis, D. J. Mullan +4
We report the white light flare rates for 10 ultracool dwarfs (UCDs) using \textit{Kepler K2} short cadence data. Among our sample stars, two have spectral type M6, three are M7, t…
