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 radius…
Heating and cooling in stellar coronae: coronal rain on a young Sun
Simon Daley-Yates, Moira M. Jardine, Craig D. Johnston
Recent observations of rapidly-rotating cool dwarfs have revealed H line asymmetries indicative of clumps of cool, dense plasma in the stars' coronae. These clumps may be either…
3D MHD models of the centrifugal magnetosphere from a massive star with an oblique dipole field
Asif ud-Doula, Stanley P. Owocki, Christopher Russell +2
We present results from new self-consistent 3D MHD simulations of the magnetospheres from massive stars with a dipole magnetic axis that has a non-zero obliquity angle () to the…
Nonideal self-gravity and cosmology: the importance of correlations in the dynamics of the large-scale structures of the Universe
P. Tremblin
Inspired by the role of correlations in the statistical mechanics of nonideal self-interacting fluids, we suggest that unresolved sub-structures (i.e. correlations) have to be take…
Non-ideal self-gravity and cosmology: the importance of correlations in the dynamics of the large-scale structures of the Universe
P. Tremblin, G. Chabrier, T. Padioleau +1
Inspired by the statistical mechanics of an ensemble of interacting particles (BBGKY hierarchy), we propose to account for small-scale inhomogeneities in self-gravitating astrophys…
Idealised 3D simulations of diabatically-forced Ledoux convection. Application to the atmosphere of hot rocky exoplanets
Simon Daley-Yates, Thomas Padioleau, Pascal Tremblin +2
We investigate the impact on convective numerical simulations of thermo-compositional diabatic processes. We focus our study on simulations with a stabilizing temperature gradient…
3D MHD simulations and synthetic radio emission from an oblique rotating magnetic massive star
Simon Daley-Yates, Ian R. Stevens, Asif ud-Doula
We have performed 3D isothermal MHD simulation of a magnetic rotating massive star with a non-zero dipole obliquity and predicted the radio/sub-mm observable lightcurves and contin…
Hot Jupiter accretion: 3D MHD simulations of star-planet wind interaction
Simon Daley-Yates, Ian R. Stevens
We present 3D MHD simulations of the wind-wind interactions between a solar type star and a short period hot Jupiter exoplanet. This is the first such simulation in which the stell…
Winds of Massive Magnetic Stars: Interacting Fields and Flow
Simon Daley-Yates, Ian Stevens
We present results of 3D numerical simulations of magnetically confined, radiatively driven stellar winds of massive stars, conducted using the astrophysical MHD code Pluto, with a…
Interacting Fields and Flows: Magnetic Hot Jupiters
Simon Daley-Yates, Ian Stevens
We present Magnetohydrodynamic (MHD) simulations of the magnetic interactions between a solar type star and short period hot Jupiter exoplanets, using the publicly available MHD co…
Sub-mm free-free emission from the winds of massive stars in the age of ALMA
S. Daley-Yates, I. R. Stevens, T. D. Crossland
The thermal radio and sub-mm emission from the winds of massive stars is investigated and the contribution to the emission due to the stellar wind acceleration region and clumping…
