A new hydrous phase, ε-AlOOH, was observed to be stable at pressures above 200 GPa. The stability of ε-AlOOH at extremely high pressures may affect the modeling results of the internal structure and deep water circulation of some extra-solar planets, such as terrestrial super-Earths, because the hydroxide may store water in these regions.
