Yann Alibert

Prof. Yann Alibert is an Affiliated Professor of Astrophysics at the University of Bern's Faculty of Science, based at the Center for Space and Habitability (CSH). His research focuses on exoplanet science, planetary formation mechanisms, and space missions like CHEOPS and PLATO. He leads observational campaigns analyzing exoplanet atmospheres, orbital dynamics, and planetary system architectures using high-precision photometry and spectroscopy.

Key areas of expertise include:

• Characterization of exoplanet atmospheres via CHEOPS and ESPRESSO
• Studying resonant planetary systems and compact multi-planet configurations
• Development of mass-radius modeling tools (e.g., mr-plotter)
• Investigating planet formation pathways through streaming instability and pebble accretion

Recent work emphasizes ultra-short-period planets, hot Jupiters, and water-world candidates. He collaborates extensively with international teams on TESS, PLATO, and ground-based radial velocity surveys. His research contributes to understanding planetary system evolution and the search for habitable worlds.
