Self-Regulating Process Governs Cosmic Order Inside Star Clusters
Astrophysicists from Nanjing University and the University of Bonn have shown that star‑mass distribution in clusters follows a self‑regulating process rather than random sampling. By applying Shannon entropy, they derived an "optimal sampling" model that predicts stellar masses from the total cluster mass alone. The study reveals that dwarf galaxies cannot produce very massive stars, while massive ellipticals can generate millions of ultra‑bright giants. This deterministic framework promises faster, less resource‑intensive galaxy‑evolution simulations.
