High sigma model of pulsar wind nebulae

04.11.2009 10:08    cita.utoronto.ca
Pulsars and central engines of long gamma ray burst -- collapsars -- may produce highly magnetized (Poynting flux dominated) outflows expanding in a dense surrounding (interstellar medium or stellar material).

Protoplanetary Disk Winds by Magnetorotational Instability : Formation of an Inner Hole and a Crucial Assist for Planet Formation

04.11.2009 10:08    cita.utoronto.ca
By constructing a global model based on 3D local magnetohydrodynamical (MHD) simulations, we show that the disk wind driven by magnetorotational instability (MRI) play a significant role in the dispersal of the gas component of proto-planetary disks.

On the relation of standard and helical magnetorotational instability

04.11.2009 10:08    cita.utoronto.ca
The magnetorotational instability (MRI) plays a crucial role for cosmic structure formation by enabling turbulence in Keplerian disks which would be otherwise hydrodynamically stable.

Magnetorotational instability in proto-neutron stars

04.11.2009 10:08    cita.utoronto.ca
Magnetorotational instability (MRI) has been suggested to lead a rapid growth of the magnetic field in core collapse supernovae and produce departures from spherical syymmetry that can be important in determining the explosion mechanism.

Large scale effects on the decay of rotating helical and non-helical turbulence

04.11.2009 10:07    cita.utoronto.ca
Decaying three-dimensional (3D) turbulence is studied via direct numerical simulations (DNS) for an isotropic non-rotating flow and for rotating flows with and without helicity.

On the Relationship between Equilibrium Bifurcations and Ideal MHD Instabilities for Line-Tied Coronal Loops

04.11.2009 10:07    cita.utoronto.ca
For axisymmetric models for coronal loops the relationship between the bifurcation points of magnetohydrodynamic (MHD) equilibrium sequences and the points of linear ideal MHD instability is investigated imposing line-tied boundary conditions.

Dual black holes in merger remnants. II: spin evolution and gravitational recoil

04.11.2009 10:07    cita.utoronto.ca
Using high resolution hydrodynamical simulations, we explore the spin evolution of massive dual black holes orbiting inside a circumnuclear disc, relic of a gas-rich galaxy merger.

Effective Inner Radius of Tilted Black Hole Accretion Disks

04.11.2009 10:07    cita.utoronto.ca
One of the primary means of determining the spin of an astrophysical black hole is by actually measuring the inner radius of a surrounding accretion disk and using that to infer the spin.
