Udry ( Geneva Observatory, Jet Propulsion Lab, Saint-Luc Observatory | | 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. | | Source: | arXiv, astro-ph/9910223 | | Services: | Forum | Review | PDF | Favorites | |
