Adjust mass, spin, and magnetic field to see how all major observational constraints update simultaneously. Each panel re-derives its key quantity in real time and links to the full tool for deeper exploration.

OC orbits with period ~370 Myr. Last pericentre at ~1.5 kpc (~0.3 Gyr ago) stripped ~3% of cluster mass per passage. Backward integration to formation suggests M₀ ≈ 5–10× current mass, consistent with a nuclear star cluster origin that could have seeded a central massive black hole.
