The messy death of a multiple star system and the resulting planetary nebula as observed by JWST
December 8, 2022
Planetary nebulae—the ejected envelopes of red giant stars—provide us with a history of the last, mass-losing phases of 90% of stars initially more massive than the Sun.
Experimental observation of open structures in elemental magnesium at terapascal pressures
September 19, 2022
Our results demonstrate that phase transformations of extremely condensed matter, previously only accessible through theoretical calculations, can now be experimentally explored.
Electron density change across the pressure-induced iron spin transition
July 6, 2022
High-pressure single-crystal x-ray diffraction is used to experimentally map the electron-density distribution changes in (Fe,Mg)O as ferrous iron undergoes a pressure-induced transition from high- to low-spin states.
On the liquid–liquid phase transition of dense hydrogen
December 15, 2021
Showing that the machine learning potential does not reproduce our still larger density functional theory molecular dynamics (DFT-MD) calculations as it should.
Scale interactions and anisotropy in Rayleigh–Taylor turbulence
November 16, 2021
Studying energy scale transfer in Rayleigh–Taylor (RT) flows by coarse graining in physical space without Fourier transforms, allowing scale analysis along the vertical direction.
