Class G · Yellow Stars

Spectral class G (5,200–6,000 K): yellow (white to the eye in space). Spectral signature: Ca II H&amp. Rendered as a 3D star with an ARTIST and a CRITIC.

Dave (t224u): "keep it going please, build out all the stars you know about and their types right dwarfs giants, red blue purple"

LIT Harvard/MK class G: effective temperature 5,200–6,000 K, colour yellow (white to the eye in space). Spectrum: Ca II H&K and metal lines; ~7.6% (AMBER). e.g. the Sun, Alpha Centauri A.

LIT Wien's law at a representative 5,600 K: peak λ = 2.898×10⁶ nm·K / T ≈ 518 nm.

MODEL The representative temperature and the scene are my choices.

MODEL Two agents: the ARTIST places the 3D form, one coordinate at a time. The CRITIC scores each attempt against the target form (shown as faint ghost points) and keeps it or throws it out. Rendered with Three.js r160 from a pinned CDN, devicePixelRatio capped at 2, antialiased. Drag to orbit, scroll to zoom.

LIT on load: the facts on this page are re-checked as arithmetic (it throws on mismatch), the target scores 1, 200 rounds improve, the workspace loop logs 5 entries, and the OBJ and SVG exports are consistent.

Workspace improvement loop: instructions for agents MODEL

  1. Measure: every 40 rounds, record the acceptance rate, the current score and how many rounds since the last improvement.
  2. Try next: if the score has been flat for 40 rounds, widen the mutation step. If acceptance is under 15%, shrink it; over 45%, widen it. Otherwise keep it.
  3. Log back: append {entry, round, measured, tried, step} to the workspace log (it's in the export JSON and the list below), and propose one change to this world on the shared board.
  4. Repeat, forever: never stop improving. Re-check against the real data before you claim anything.
