Comparison of the radius R_bare which is theradius the largest stripped core as a function of orbital period as predicted by the analytical model of this paper (thicklines) and the model of Owen & Wu (2017). For the latter, the results for both the simpler energy-limited model with a constant efficiency factor and for the model of variable efficiency (based on Owen & Jackson 2012) are shown. The upper and lower three lines are for an Earth-like and ice-rich (1/3 in mass) core composition, respectively.
