Par Domenico Barbato (INAF)

The growing field of comparative exoplanetology increasingly relies on complementary detection technique to fully characterize planetary system architectures. Yet, estimates of exoplanet occurrence rates often remain constrained by the detection capabilities of individual instruments, surveys, or techniques. The resulting heterogeneity can limit our ability to construct a coherent view on exoplanetary demographics.

In this talk, I’ll present an in-development, multi-technique tool that jointly evaluates detection completeness of any combination of radial velocity, transit, proper motion anomaly and imaging data to pave the way towards multi-technique exoplanetary demographics. I present initial results, as well as highlighting both the methodological challenges yet to overcome and the implications for our understanding of the formation and evolution of planetary systems.
