Biosignature Disequilibrium Map — Transit Photometry & Photochemistry Phase Space

Interactive 2D exoplanet transit-photometry and photochemistry-phase-space simulator: watch an exact sky-plane occultation light curve deepen in the O2 band while a live parameter-space heatmap shows whether your biosphere/volcanism/UV mix reads as a genuine chemical-disequilibrium biosignature or an abiotic false positive.

A 2D-native pair to the 3D transit simulator: an exact sky-plane occultation diagram computes the transit light curve from real circle-overlap geometry instead of a flattened camera view, a rolling strip chart shows the dip deepening in the O₂ band versus the featureless continuum, a transmission-spectrum panel reads out the absorption bands, and a live parameter-space heatmap sweeps the whole biosphere × volcanism grid so you can see where a genuine chemical-disequilibrium biosignature separates from an abiotic false positive.

⚙ Under the hood

An exact sky-plane occultation diagram computes a real exoplanet transit light curve from circle-overlap geometry, then a live parameter-space heatmap sweeps the whole biosphere/volcanism grid so you can see at a glance where a genuine O2+CH4 chemical-disequilibrium biosignature separates from an abiotic false positive.
