PLATO’s yield with YETI FUR - Choose your science

With 4 years of observations and a field of view 24 times bigger than Kepler, PLATO will with no doubt find thousands of exoplanets of all varieties.

More than detection, its sensitivity and target selection will enable the mission to characterise exoplanets with unprecedented precision.

In order to get an idea of what to expect from the mission, we perform simulations of photometric transit and radial velocity follow-up observations for each star of the PLATO Input Catalog (PIC). We opted for a modular approach which allows us to explore and understand the influence of various parameters, including observing strategies, stellar parameters, or several mass-radius relationships for planets. This approach will also enable us to apply our yield estimator to other missions in the future. 

We present here estimations of the yield of characterised planets (3% precision on radii and 10% on the mass), not only by the PLATO satellite itself, but also by its follow-up in radial velocity measurements. YETI FUR also calculates the follow-up time that will be necessary to reach the required precision on the mass which will enable exoplanet classification (gaseous, rocky, etc. ). Furthermore, one of the main output from YETI FUR is a mock-up table of the exoplanets around the stars of PLATO, with a variety of parameters (mass, radius, precisions, etc.), that can be used as input for other works exploring other aspects of the PLATO mission (e.g. target selection for the Follow-Up)
