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.
Canonical reference: M = 8,200 M☉ (Häberle 2024), d = 5,494 pc (Häberle 2025), a = 0.9 (assumed)
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.
First stellar-mass black hole confirmed in Omega Centauri: a 4.46 M☉ BH in a 94-yr binary with a 0.78 M☉ main-sequence star, found astrometrically from 20+ yr of HST data plus JWST — the longest-period BH binary known. Cluster models predict ~10⁴ such BHs; this first confirmed member is direct evidence for the extended-central-mass (BH cluster) alternative that the Bañares 2025 timing limit favors over a single IMBH.
