Explore V381 Normae (XTE J1550−564), a powerful galactic microquasar. Watch a 9.1-solar-mass black hole tug on an orange K subgiant star during a rapid 1.54-day orbital dance.

Discover V404 Cygni, a famous 9-solar-mass black hole binary. Watch a tidally distorted K-giant donor star fill its Roche lobe and whip around the black hole every 6.47 days in 3D.

Explore V518 Persei (GRO J0422+32), one of the lowest-mass black hole candidates known. Track a 4-solar-mass compact object and its red dwarf donor star on a 5.1-hour orbit.

Discover V616 Monocerotis (A0620−00), one of Earth's closest stellar-mass black holes. Watch a 6.6-solar-mass black hole orbit an orange dwarf star every 7.75 hours in Newtonian 3D.

Simulate V821 Arae (GX 339−4), a prominent low-mass X-ray binary. Watch a 9-solar-mass black hole gravitationally capture material from an orbiting companion star on a 1.76-day path.

Experience XTE J1650−500, home to one of the lightest stellar-mass black holes cataloged. Trace a 5-solar-mass black hole and its companion K dwarf circling every 7.7 hours in 3D.
