Ben W.P. Lew
Astronomer affiliated with the Bay Area Environmental Research Institute and nasa-ames-research-center. Lead author of the 2026 AJ paper “JWST Spectral Retrieval of Cold Directly Imaged Planet WD 0806b and the First Measurement of Altitude-dependent K_zz in Exoplanet Atmospheres” (summarized in src-aas-nova-wd-0806b-atmosphere-2026-04). The paper provided the first observational evidence that bulk mixing weakens with altitude in an exoplanet atmosphere — a constraint for exoplanet-atmosphere-models.
