Intrinsic Magnetism in Accretion Discs,ndard mean-field dynamos are considered, which can generate large-scale magnetic fields in discs. Toroidal magnetic field is generated by the shearing of the radial field, while turbulence with Coriolis force and vertical stratification lead to the .-effect which converts toroidal field to poloidal

Stellar Magnetic Winds,es the generation of large-scale magnetic fields in such stars very likely, and magnetically influenced wind flows from the stellar surface would then lead to magnetic braking. The secondary would be spun down to an under-synchronous state and tides would then operate to spin the star up at the expe

Accretion Disc Magnetic Winds, become collimated parallel to the disc rotation axis. It is known that a differentially rotating, turbulent disc can have a large-scale magnetic field generated by dynamo action. Magnetically channelled winds are effective at removing angular momentum from accretion discs, provided that the initial

AM Her Stars: Stream Channelling and the Accretion Torque,cretion torques are considered here, as well as the effects of partial field channelling. For a dipolar magnetic field and moderate degrees of asynchronism, the normal components of the accretion torque average to zero over a synodic rotation period, while the parallel component has a conservative averaged form for total field channelling.

Disc Disruption and Accretion Curtains, vertical expansion due to magnetic heating. Expanding material can be accelerated through a sonic point and then flow through a magnetically channelled curtain region to accrete on to the star through a narrow shock region. A detailed study of disc disruption and the curtain flow is presented here.

Stellar Magnetic Winds,ere, with particular emphasis on the fast rotator regime. This is applied to derive mass transfer rates in binaries with periods ≳ 3.0 h, for a range of laws relating the secondary’s surface magnetic field to its rotation rate. Explanations for the period gap, and why AM Herculis binaries appear not to be affected by the gap, are discussed.

Magnetism in Binary Stars,scs..Sub-thermal magnetic fields lead to a magnetorotational instability in accretion discs which is believed to be the source of the turbulent viscosity needed to account for the inflow. Disc dynamos can generate large-scale magnetic fields which can lead to radial transport of angular momentum, or
