HD88986 radial velocity curves : J/A+A/681/A55

Dataset

Description

We present the detection and characterization of HD88986 b, a potentially transiting sub-Neptune, possessing the longest orbital period among known transiting small planets (<4R_{sun}_) with a precise mass measurement (sigma_M_/M>25%). Additionally, we identified the presence of a massive companion in a wider orbit around HD88986. Radial velocities used in the paper.
