GPX-1b: discovery of a brown-dwarf planet around a star

GPX-1b: discovery of a brown-dwarf! On 2017 and 2018, our friend Paul Benni, observed a large fields in northen sky searching for exoplanet during his campain called GPX (Galactic Plane eXoplanet search). We were happy to join in this project. And we were always active to follow-up his target. One of this target was the […]
