A low-mass planet candidate orbiting Proxima Centauri at a distance of 1.5 AU.

The article repots on orbit Proxima Centauri at a distance of 1.5 AU. Topic include measurements with the High Accuracy Radial Velocity Planet Searcher (HARPS) and Ultraviolet and Visual Echelle Spectrograph (UVES); and investigating the nature of this signal in detail, checked its evolution and stability over time by analyzing the stacked Bayesian GLS (SBGLS).
