Extended Data Fig. 3: Partition coefficients of H2O.
From: The interior as the dominant water reservoir in super-Earths and sub-Neptunes
Calculated partition coefficients of H2O between iron and silicate melts (\({D}_{{{\rm{H}}}_{2}{\rm{O}}}^{{\rm{Fe}}/{\rm{MgSi}}{{\rm{O}}}_{3}}\)) as a function of its concentrations in iron melt (\({X}_{{{\rm{H}}}_{2}{\rm{O}}}^{{\rm{Fe}}}\)) at different temperatures under 500 GPa (a) and 1000 GPa (b). The 1 s.d. uncertainties of \({D}_{{{\rm{H}}}_{2}{\rm{O}}}^{{\rm{Fe}}/{\rm{MgSi}}{{\rm{O}}}_{3}}\) at 8600 and 13000 K are represented by the shaded area.
