  "caption": "MESA uses its full ordinary EOS and opacity with pure hydrogen, zero seed metals and no nuclear reactions or nuclear heating. The display starts at 1,000 years; the data file retains the full histories. Models reach a declared cooling endpoint after central temperature falls below half its peak and electrons are degenerate. The one-solar-mass refinement changes peak temperature by 0.061% and endpoint age by 1.5%. These are the public contraction-only limiting experiment, not fully matched unbound-deuteron stars or estimates of habitability.",
