Explore the cluster

Hands-on pieces built straight from my real Jaxstro models — for curiosity, for talks, for the classroom. Drag, zoom, and turn the knobs; the physics is honest, not decorative.

  • Mass segregation

    Turn one knob and watch the most massive stars sink to the cluster core — primordial mass segregation, computed live from the real density-coupling used in progenax.

  • Gas expulsion

    Massive-star feedback drives the natal gas outward, unbinding the cloud and leaving the young cluster behind. Scrub the expulsion or let it play.

  • Birth of a cluster

    A turbulent cloud grows dense, ignites its stars, and blows itself clear with feedback — the life of a star cluster, told scroll by scroll from a real gravoturb model.

  • Inference in progress

    Watch a posterior over a cluster's mass, age, and size tighten as observations arrive — real differentiable inference from informax, on a synthetic cluster.

The universe may be cruel, but at least it's consistent.
