Combined Radial-velocity and astrometry modelling to constrain the population of wide-orbiting gas giants

We use precision radial-velocity instruments in Chile to uncover the first Jupiter-analogues orbiting metal-rich stars.  The key to our project is the combination with space-based astrometric measurements taken by Hipparcos and Gaia, whereby we are developing statistical models that can search the parameter space using a joint model to not only detect these planets, but also to measure their absolute masses and orbital characteristics.

Type of project: PhD thesis
