Improved Parameters for Extrasolar Transiting Planets

摘要: We present refined values for the physical parameters of transiting exoplanets, based on a self-consistent and uniform analysis transit light curves observable properties host stars. Previously it has been difficult to interpret ensemble exoplanets because widely different methodologies that have applied in individual cases. Furthermore, previous studies often ignored an important constraint mean stellar density can be derived directly from curve. The main contributions this work are (1) critical compilation error assessment all reported effective temperature metallicity stars, (2) application consistent methodology treatment errors modeling curves, (3) more accurate estimates mass radius evolution models, incorporating photometric density. use our results revisit some previously proposed patterns correlations within ensemble. confirm mass-period correlation find evidence new pattern scatter about correlation: planets around metal-poor stars massive than those metal-rich at given orbital period. Likewise, we dichotomy according their Safronov number, systems with small numbers average. Finally, trend led suggestion higher harbor greater heavy-element content.
