Enhanced constraints on the interior composition and structure of terrestrial exoplanets

Wang, Haiyang S.; Liu, Fan; Ireland, Trevor; Brasser, R.; Yong, David; Lineweaver, Charles


Exoplanet interior modelling usually makes the assumption that the elemental abundances of a planet are identical to those of its host star. Host stellar abundances are good proxies of planetary abundances, but only for refractory elements. This is particularly true for terrestrial planets, as evidenced by the relative differences in bulk chemical composition between the Sun and the Earth and other inner Solar system bodies. The elemental abundances of a planet host star must therefore be...[Show more]
