University of Zurich

Swiss research university. Hosts the planetary-interior modeling work of ravit-helled and simon-muller, who contributed the toi-5205-b interior models reported in src-sciencedaily-forbidden-exoplanet-atmosphere-2026-04. Their models imply the bulk planet is ~100× more metal-rich than the visible atmosphere — interpreted as inward heavy-element migration and the cessation of interior–atmosphere mixing.
