      abstract     = {A new diamond anvil cell experimental approach has been
                      implemented at the European x-ray Free Electron Laser,
                      combining pulsed laser heating with MHz x-ray diffraction.
                      Here, we use this setup to determine liquidus temperatures
                      under extreme conditions, based on the determination of
                      time-resolved crystallization. The focus is on a Fe-Si-O
                      ternary system, relevant for planetary cores. This
                      time-resolved diagnostic is complemented by a finite-element
                      model, reproducing temporal temperature profiles measured
                      experimentally using streaked optical pyrometry. This model
                      calculates the temperature and strain fields by including
                      (i) pressure and temperature dependencies of material
                      properties, and (ii) the heat-induced thermal stress,
                      including feedback effect on material parameter variations.
                      Making our model more realistic, these improvements are
                      critical as they give 7000 K temperature differences
                      compared to previous models. Laser intensities are
                      determined by seeking minimal deviation between measured and
                      modeled temperatures. Combining models and streak optical
                      pyrometry data extends temperature determination below
                      detection limit. The presented approach can be used to infer
                      the liquidus temperature by the appearance of SiO2
                      diffraction spots. In addition, temperatures obtained by the
                      model agree with crystallization temperatures reported for
                      Fe–Si alloys. Our model reproduces the planetary relevant
                      experimental conditions, providing temperature, pressure,
                      and volume conditions. Those predictions are then used to
                      determine liquidus temperatures at experimental timescales
                      where chemical migration is limited. This synergy of novel
                      time-resolved experiments and finite-element modeling pushes
                      further the interpretation capabilities in diamond anvil
                      cell experiments.},
