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, a_v > 0.1)

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

"WEAK" PROPELLER, NO OUTFLOWS

• Smaller accretion rate
(viscosity is low, a_v < 0.1)

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