Super-Keplerian Equatorial Outflows in SS 433. Centrifugal Ejection of the Circumbinary Disk

Understand

The microquasar SS 433 is the only known steady supercritical accretor in the Galaxy.

• It is well-known for its relativistic baryonic jets, but the system also drives equatorial outflows.
• These have been routinely detected in radio images, and components associated with a circumbinary disk have also been suggested in optical emission lines.
• We wish to spatially resolve the regions producing the stationary emission lines of SS 433 to shed light on its circumbinary structure and outflows.
