orbital-thermal-bounds — Wiki

orbital-thermal is a dependency-light, audit-closed Python package for reduced-order orbital data-center radiator modeling. It turns the analytic thermodynamic bounds of the bounds preprint into executable functions and extends them to the time-dependent, environment-coupled regime: a panel with thermal mass whose effective radiative sink changes around its orbit.

Its headline result is a quantified, independently verified correction to a published public model: at the default edge-on geometry, replacing an approximate Earth view factor with the exact one raises the predicted equilibrium temperature by +6.35 K. The archived paper-three record is 10.5281/zenodo.20695720; the repository also links the broader Zenodo record at 10.5281/zenodo.20695719.

Version note. These instructions describe release v1.0.0. For exact reproduction of the published paper-three results, check out the v1.0.0 tag rather than the moving main branch.
