Dust cloud lifetimes of Scallop-shell stars
Simon Daley-Yates, Moira M. Jardine, Luke Bouma
We investigate the survival of dust trapped in magnetically confined cool gas clouds (or {\it prominences}) around rapidly rotating M-dwarfs exhibiting the ``scallop-shell'' light-…
Electron Cyclotron Maser Emission from Ejected Stellar Prominences on V374 Peg
C. E. Brasseur, M. M. Jardine, S. Daley-Yates +2
We investigate a possible origin for bursty radio emission observed on the active M dwarf V374 Peg, combining data-driven magnetic field modelling with archival radio light curves.…
WASP-12, shrouded in mystery or just cold gas?
Simon Daley-Yates, Ricarda Beckmann, Lewis McCallum +2
Observations of the planet-hosting star WASP-12 show a distinctive depression in the \ion{Mg}{ii} and \ion{Ca}{ii} resonance lines. This has been interpreted as a marker of atmosph…
Filament Mass Losses Forced by Magnetic Reconnection in the Solar Corona
Craig D. Johnston, Lars K. S. Daldorff, Peter W. Schuck +4
Recent observations of the solar atmosphere in cool extreme ultraviolet (EUV) lines have reported the prevalence of coronal rain falling from coronal cloud filaments that are assoc…
Radio Signatures of Star-Planet Interactions, Exoplanets, and Space Weather
J. R. Callingham, B. J. S. Pope, R. D. Kavanagh +22
Radio detections of stellar systems provide a window onto stellar magnetic activity and the space weather conditions of extrasolar planets, information that is difficult to attain…
Simulating stellar coronal rain and slingshot prominences
Simon Daley-Yates, Moira Jardine
We have numerically demonstrated that simulated cool star coronae naturally form condensations. If the star rotates slowly, with a co-rotation radius greater than the Alfvén radiu…
