MHD SIMULATIONS OF DISK - MAGNETIZED STAR INTERACTIONS IN QUIESCENT REGIME: FUNNEL FLOWS AND ANGULAR MOMENTUM TRANSPORT

2D MHD (axisymmetric) numerical simulations of disk accretion to a star with a dipole magnetic field

 

Disk accretion to a slowly rotating star (r_cor = 3). Viscosity parameter a = 0.02. Initially, inner radius of the disk located at the magnetosphere radius, r_m = 1. 
[video] (.avi,  approx. 1.7 MBt)

 

Disk accretion to a slowly rotating star (r_cor = 3). Viscosity parameter a = 0.02. Initially,  inner radius of the disk is at co-rotation radius, r_cor = 3. 
[video] (.avi,  approx. 1.9 MBt)

 

Disk accretion to a slowly rotating star (r_cor = 3). Viscosity parameter a =0. Initially,  inner radius of the disk is at co-rotation radius, r_co r= 3. 
[video] (.avi,  approx. 1.1 MBt)

 

Disk accretion to a slowly rotating star (r_cor = 3). Viscosity parameter a =0. Initially,  inner radius of the disk is at co-rotation radius, r_co r= 3. Smaller region is shown.
[video] (.avi,  approx. 1.3 MBt)

 

Torqueless accretion which is realized at co-rotation radius r_cor = 1.5 (see Paper). Viscosity parameter is a =0.02.
Initially, inner radius of the disk located at the magnetosphere radius, r_m = 1.
