- temperature and intensity of the winds à powerful magnetic fields must be present to create magnetic turbulence
à friction in the gaseous disk and drive winds from the disk that carry momentum outward as the gas falls inward.

- Magnetic friction also heats the gas in the inner part of the disk to X-ray emitting temperatures

- black hole, mass 7x sun

- "microquasar" because it produces a large amount of energy from a small volume of space

- an aging, bloated star and a black hole orbit each other once every 2.6 days.

- The black hole steals gas from the star

- Accretion disc around the black hole

- two strong jets of material flowing away from its poles, consisting of material in the accretion disk
that is accelerated to almost the speed of light by the disk's strong magnetic field - "superluminal,"
meaning that it's material moves faster than lightspeed.
Further observations shows that the material is actually moving at just less than lightspeed,

- moving through the galaxy at about 250,000 miles per hour (400,000 km per hour).
This supports the idea that the black hole formed from the collapse of the core of a massive star.
As the core collapsed, its outer layers exploded as a supernova.
The explosion was a little off-centered, though, so it sent the system racing through the galaxy.

- black hole is rotating. Its rotation pulls along the interior of the accretion disk -- and even the fabric of space itself

- first black hole found to be moving fast through the plane of our galaxy

- moving through the Milky Way at around 250,000 miles per hour (112 km/s)
