Abstract Recent progress in hypotheses of planetrary accretion, together with improved knowledge of thermal evolution of the Earth's core, call for a model, concerning thermal effects of core formation. We present calculations of the temperature distribution T(t,r) during core formation, assuming Safronov's accretion theory in empty space. Main feature is a stable core at the end of accretion, coming in dispute with paleomagnetic demands. We favour a scenario, basing on the evolution of a gaseous disk of moderate mass and producing primordial atmospheres at the end of terrestrial planet accretion.
