Prediction of a hexagonal SiO2 phase affecting stabilities of MgSiO3 and CaSiO3 at multimegabar pressures
T Tsuchiya, J Tsuchiya - Proceedings of the National …, 2011 - National Acad Sciences
Ultrahigh-pressure phase relationship of SiO2 silica in multimegabar pressure condition is
still quite unclear. Here, we report a theoretical prediction on a previously uncharacterized …

Rocky core solubility in Jupiter and giant exoplanets
HF Wilson, B Militzer - Physical Review Letters, 2012 - APS
Gas giants are believed to form by the accretion of hydrogen-helium gas around an initial
