Title: The TROY project: the search for extrasolar trojan planets Abstract: As the field of extrasolar planets evolves with numerous discoveries of new and diverse planets, we can start thinking in more challenging (observationally talking) scientific cases that can bring up new, hidden, pieces of the exoplanetary science puzzle. This is the case of the TROY project, a multi-technique effort to look for the first co-orbital planets and to provide estimates of the occurrence rate of these bodies down to the Earth-mass regime. Despite being missed in our Solar System, where only kilometer-size (or smaller) bodies co-rotate with most of the planets, theory allows even equal-mass planets to co-exist in the same orbit. I this poster I will present the news on the TROY project including the last ground-based observations, the results from the first radial velocity search involving 46 planetary systems (Lillo-Box et al., 2018) and showing the first results from our Kepler/K2 search.
