Metallicity, planetary formation and migration | M. Livio

23 Oct 2003 | Journal: | Mon.Not.Roy.Astron.Soc. 346 (2003) L42 | Subject: | astro-ph | Abstract: | Recent observations show a clear correlation between the probability of hosting a planet and the metallicity of the parent star. Since radial velocity surveys are biased, however, towards detecting planets with short orbital periods, the probability-metallicity correlation could merely reflect a dependence of migration rates on metallicity. We investigated the possibility, but find no basis to suggest that the migration process is sensitive to the metallicity. The indication is, therefore, that a higher metallicity results in a higher probability for planet formation. | Source: | arXiv, astro-ph/0310695 | Services: | Forum | Review | PDF | Favorites |
