ACCRETION TO DIPOLE IN THE PROPELLER REGIME
I. STATIONARY STAR
MHD Simulations of Accretion
to a Star in the "Propeller" Regime
This
work investigates spherical accretion
to a rotating magnetized star in the "propeller" regime using
axisymmetric resistive,
magnetohydrodynamic
simulations. In this regime accreting matter tends to be expelled from the
equatorial region of the
magnetosphere
where the centrifugal force on matter rotating with the star exceeds the
gravitational force.

II. MOVING STAR
Spinning-Down of Moving
Magnetars in the Propeller Regime
Using
axisymmetric MHD simulations we have studied the supersonic propagation
through the ISM of magnetars in the propeller stage. We have done many
simulation runs for the purpose of determining the angular momentum loss
rate of the star due to the interaction of its magnetosphere with the
shocked ISM.
