Trojan planets
In April 2023, a group of amateur astronomers reported two new exoplanet candidates co-orbiting, in a horseshoe exchange orbit, close to the star GJ 3470 (this star has a confirmed planet GJ 3470 b). However, the mentioned study is only in preprint form on arXiv, and it has not yet been peer reviewed and published in a reputable scientific journal. Unrelated to the aforementioned claim, a strong candidate of a trojan planet in the GJ 3470 system was found by the TROY project and published in Astronomy & Astrophysics, based on the radial velocity data.
