Director of Beijing Astronomical Observatory
About Tian Chen
In 2019, Tian Chen led the calibration team that enabled China’s FAST telescope to detect its first exoplanet candidate orbiting a K-dwarf, using a novel Doppler tomography method refined during joint observations with Chile’s ALMA array. Unlike many contemporaries who prioritize instrument development alone, Tian insists on embedding open-data protocols into every mission architecture, co-authoring the Beijing, Geneva Framework for Shared Solar Wind Data in 2022. Fluent in Mandarin, English, and basic Swahili (learned while mentoring Tanzanian students at the Sino-African Space Science Workshop), they’ve restructured the Observatory’s visitor program to include live translation of public star parties into Uyghur and Tibetan. Their office wall holds not awards, but three hand-drawn star charts, one from a Mongolian herder’s child, one from a Jakarta high-schooler, and one from their own daughter, annotated with orbital corrections in red pencil.
