Stability of the MgSiO3 analog NaMgF3 and its implication for mantle structure in super-Earths
First-principles calculations on MgSiO(subscript 3) suggested a breakdown into MgO + SiO(subscript 2) at pressure above 1000 GPa with an extremely large negative Clapeyron slope, isolating the lowermost mantles of larger super-Earths (∼10M ⊕) from convection. Similar calculations predicted the same...
