An exoplanet in orbit around τ 1 Gruis Hugh


We report the detection of a new candidate exoplanet around the metalrich star τ Gruis. With M sin i = 1.23±0.18 MJUP, a period of 1326±300 d and an orbit with an eccentricity of 0.14±0.14 it adds to the growing population of long period exoplanets with near-circular orbits. This population now comprises more than 20% of known exoplanets. When the companion… (More)
