An Exoplanet Model for the Carbon Cycle

“We don’t know if there are any other planets at all with plate tectonics and a carbon cycle. In our solar system, the Earth is the only planet where we have found a carbon cycle. We hope that our model can contribute to the discovery of an exoplanet with a carbon cycle, and therefore, possibly life.”
