The search for life on planets beyond our solar system mainly focuses on the characterization of atmospheres. In this project, we study the impact of bioweathering on the long-term water and carbon cycles and implications on the observed exoplanet spectra. This will be achieved by merging surface and subduction zone processes with evolution models of the interior of planets. The goal is to gain insights into the habitability and a potential biosphere of planets beyond our solar system by investigating the atmospheric water and carbon dioxide budgets in conjunction with other exoplanet parameters.
The project will be executed within the groups of Wim van Westrenen, Vrije Universiteit Amsterdam, and Carsten Dominik, Universiteit van Amsterdam. Principal investigator is Dennis Hoening.
