SS 433—Concerning the Slaved Accretion Disk

Abstract:
The Galactic microquasar SS 433 is a black hole that super-Eddington accretes from a disk fed from a Companion. The famous jets precess about an axis believed to be controlled by the feed; slaved precession. Variations in the polar angle of the precessing jets in SS 433 are negatively correlated with variations in the speed of the jets. This curious correlation has never been explained; here I consider a mechanism involving the effect of flares on the slavery. Recent observations of speed variation of the X-ray jets, with a period of ∼6 days, have a natural place in this slaved disk scenario.
