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.
