Radial velocity follow-up of GJ1132 with HARPS: A precise mass for planet b and the discovery of a second planet

The source GJ1132 is a nearby red dwarf known to host a transiting Earth-size planet. After its initial detection, we pursued an intense follow-up with the HARPS velocimeter. We now confirm the detection of GJ1132b with radial velocities alone. We refined its orbital parameters, and in particular, i...
