TL;DR
This paper reports the detection of a 4MJ exoplanet orbiting Gliese 86 with a 15.8-day period, along with a more massive companion, highlighting the correlation between close-in planets and higher stellar metallicity.
Contribution
First detection of a planet orbiting Gliese 86 using radial velocity measurements, and analysis of metallicity trends in close-in planetary systems.
Findings
A 4MJ planet with a 15.8-day orbit was detected.
A second more massive companion was identified.
Close-in planets are associated with higher stellar metallicity.
Abstract
A 4MJ planet with a 15.8day orbital period has been detected from very precise radial velocity measurements with the CORALIE echelle spectrograph. A second remote and more massive companion has also been detected. All the planetary companions so far detected in orbit closer than 0.08 AU have a parent star with a statistically higher metal content compared to the metallicity distribution of other stars with planets. Different processes occuring during their formation may provide a possible explanation for this observation.
