DISK ACCRETION TO MAGNETIZED STARS

THE PROPELLER REGIME OF DISK ACCRETION TO A RAPIDLY ROTATING MAGNETIZED STAR

"STRONG" PROPELLER WITH OUTFLOWS

Larger accretion rate
(viscosity is high, av > 0.1)

Diffusivity is high (ad > 0.1) and matter penetrates to the region of fast rotating magnetosphere

Strong propeller

"WEAK" PROPELLER, NO OUTFLOWS

Smaller accretion rate
(viscosity is low, av < 0.1)

Diffusivity is low (ad < 0.1) and there is no sufficient interaction between magnetosphere and the disk
