cds-question@unistra.frchemical-abundancesmultiple-starssolar-system-planetsPrior work has found that a variety of terrestrial planetary compositions are expected to occur within known extrasolar planetary systems. However, such studies ignored the effects of giant planet migration, which is thought to be very common in extrasolar systems. Here we present calculations of the compositions of terrestrial planets that formed in dynamical simulations incorporating varying degrees of giant planet migration. We used chemical equilibrium models of the solid material present in the disks of five known planetary host stars: the Sun, GJ 777, HD4203, HD19994, and HD213240. Giant planet migration has a strong effect on the compositions of simulated terrestrial planets as the migration results in large-scale mixing between terrestrial planet building blocks that condensed at a range of temperatures. This mixing acts to (1) increase the typical abundance of Mg-rich silicates in the terrestrial planets' feeding zones and thus increase the frequency of planets with Earth-like compositions compared with simulations with static giant planet orbits, and (2) drastically increase the efficiency of the delivery of hydrous phases (water and serpentine) to terrestrial planets and thus produce waterworlds and/or wet Earths. Our results demonstrate that although a wide variety of terrestrial planet compositions can still be produced, planets with Earth-like compositions should be common within extrasolar planetary systems.2012ApJ...760...44Chttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/ApJ/760/44CatalogResearchIsServedByTAP VizieR generic servicerelated-toJ/A+A/562/A71 : Abundances of solar neighbourhood dwarfs (Bensby+, 2014)J/A+A/554/A84 : Abundances of evolved stars (Maldonado+, 2013)J/A+A/552/A119 : Planet-star and moon-planet interaction (Saur+, 2013)J/A+A/552/A6 : Abundances of F-G stars (Gonzalez Hernandez+, 2013)J/A+A/551/A112 : Metallicity-giant planet correlation (Mortier+, 2013)J/A+A/541/A40 : Metallicity of solar-type stars (Maldonado+, 2012)J/ApJ/747/35 : HST/WFC3 transit observation of GJ1214b (Berta+, 2012)J/ApJ/735/41 : Carbon and oxygen abundances in FGK stars (Petigura+, 2011)J/A+A/536/A71 : Atmospheric parameters of nearby giant stars (Jones+, 2011)J/ApJ/725/2349 : C/O vs Mg/Si of planetary systems (Delgado Mena+, 2010)J/ApJ/720/1592 : Abundances of solar analogs with planets (Hernandez+, 2010)J/ApJ/715/1050 : Predicted abundances for extrasolar planets.
