HD 3167 is a bright (V=8.9 mag) K0 V star observed by the NASA’s K2 space mission during its Campaign 8. It has been recently found to host two small transiting planets, namely, HD 3167 b, an ultra short period (0.96 d) super-Earth, and HD 3167 c, a mini-Neptune on a relatively long-period orbit (29.85 d). Here we present an intensive radial velocity follow-up of HD 3167 performed with the FIES@NOT, HARPS@ESO-3.6m, and HARPS-N@TNG spectrographs. We revise the system parameters and determine… CONTINUE READING
