KnuthLab Exoplanet Catalogue (back)
Welcome to the KnuthLab Exoplanet Catalogue.
This catalogue lists exoplanets that our lab has studied and characterized. In the tables below we list the model parameters describing each planetary system. Highlighted in light green are the parameter values that we have estimated along with their associated uncertainties.
