Magnetically moderated outbursts of WZ Sagittae
O. M. Matthews, R. Speith, G. A. Wynn +1
We argue that the quiescent value of the viscosity parameter of the accretion disc in WZ Sge may be alpha_{cold}~0.01, in agreement with estimates of alpha_{cold} for other dwarf n…
Propeller activated resonances and the fate of short period cataclysmic variables
O. M. Matthews, P. J. Wheatley, G. A. Wynn +1
We show that the combination of a weak magnetic propeller and accretion disc resonances can effectively halt accretion in short period cataclysmic variables for large fractions of…
Modeling the Photopolarimetric Variability of AA Tau
Mark O'Sullivan, Michael Truss, Christina Walker +4
We present Monte Carlo scattered light models of a warped disk that reproduce the observed photopolarimetric variability of the classical T Tauri star AA Tau. For a system inclinat…
The steady-state structure of accretion discs in central magnetic fields
O. M. Matthews, R. Speith, M. R. Truss +1
We develop a new analytic solution for the steady-state structure of a thin accretion disc under the influence of a magnetic field that is anchored to the central star. The solutio…
Outbursts of WZ Sagittae
O. M. Matthews, M. R. Truss, G. A. Wynn +1
The outbursts of the dwarf nova WZ Sagittae occur on timescales which are much longer than expected from the standard thermal viscous disc instability model, which correctly reprod…
Outbursts of Young Stellar Objects
O. M. Matthews, R. Speith, G. A. Wynn
We argue that the outbursts of the FU Orionis stars occur on timescales which are much longer than expected from the standard disc instability model with α_{c} \gtrsim 10^{-3}. The…
