MHD SIMULATION OF SPHERICAL ACCRETION TO A STAR IN THE "PROPELLER" REGIME

 

Spherical accretion to a rapidly rotating star. Matter flow in the "propeller" regime for a star rotating at W*=0.5 WK* 
The axes are measured in units of the star's radius. The background represents the density and the length of the arrows is proportional to the poloidal velocity. The thin solid lines are magnetic field lines. 
[video] (.avi,  approx. 0.9 MBt)

Spherical accretion to a moderately rotating star. Matter flow in the "propeller" regime for a star rotating at W*=0.2 WK* 
The axes are measured in units of the star's radius. The background represents the density and the length of the arrows is proportional to the poloidal velocity. The thin solid lines are magnetic field lines.
