Exoworld Habitability Tuner

Dial in a hypothetical planet and host star. The Habitability Chance Index recomputes live, using VetStar's six-component scoring from eagnespuerto/vetstar.

Host star — spectral class

Orbital distance 1.00 AU

Planet radius 1.00 R⊕

STEHM atmosphere-retention threshold ≈ 0.8 R⊕; above ~2.2 R⊕ likely sub-Neptune.

Planet mass 1.00 M⊕

ExoFOP disposition

Pipeline vetting verdict

TESS sectors with a detected dip 3 / 4

Top: sectors observed · Bottom: sectors showing the transit.

Model caveats

Scoring ported verbatim from backend/app/habitability.py — weighted components: size 30 · zone 25 · star 15 · disposition 15 · flags 10 · sectors 5. Habitable-zone edges use Kopparapu et al. (2013/2014); size thresholds from Hill et al. (2026), STEHM, arXiv:2605.00170. First-order estimate, not a vetting verdict.
