Title: A correlation between the heavy element content of transiting extrasolar planets and the metallicity of their parent stars
Authors: Tristan Guillot, Nuno C. Santos, Frederic Pont, Nicolas Iro, Claudio Melo, and Ignasi Ribas

Abstract:
Nine extrasolar planets with masses between 110 and 430 earth masses are known to transit their star. The knowledge of their masses and radii allows an estimate of their composition, but uncertainties on equations of state, opacities and possible missing energy sources imply that only
inaccurate constraints can be derived when considering each planet separately.
