The first planetary candidate discovered by Latham et al. (1989) with radial velocities around a solar-like star other than the Sun, HD 114762 b, was detected with a minimum mass of 11 Mjup. The small v sin(i)~0 km/s that is otherwise measured by spectral analysis indicated that this companion of a late-F subgiant star better corresponds to a massive brown dwarf (BD) or even a low-mass M-dwarf seen nearly face-on. To our knowledge, the nature of HD 114762 b is still undetermined. The… Expand

No significant correlation between radial velocity planet presence and debris disc properties
We investigate whether the tentative correlation between planets and debris discs which has been previously identified can be confirmed at high significance. We compile a sample of 201 stars withExpand
