Ab initio prediction of an order-disorder transition in MgGeO: implication for the nature of super-Earth's mantles
Koichiro Umemoto, Renata M. Wentzcovitch
Here we present an ab initio prediction of an order-disorder transition (ODT) from -type to a ThP-type phase in the cation sublattices of MgGeO, a post-…
Geometrical Characterization of Glass Nanopipettes with Sub-10 nm Pore Diameter by Transmission Electron Microscopy
Kazuki Shigyou, Linhao Sun, Riku Yajima +9
Glass nanopipettes are widely used for various applications in nanosciences. In most of the applications, it is important to characterize their geometrical parameters, such as the…
Planetesimal formation around the snow line: I. Monte Carlo simulations of silicate dust pile-up in a turbulent disk
Shigeru Ida, Tristan Guillot, Ryuki Hyodo +2
Context: The formation of rocky planetesimals is a long-standing problem in planet formation theory. One of the possibilities is that it results from gravitational instability as a…
The impact of pre-main sequence stellar evolution on midplane snowline locations and C/O in planet forming discs
James M. Miley, Olja Panić, Richard A. Booth +3
We investigate the impact of pre-main sequence stellar luminosity evolution on the thermal and chemical properties of disc midplanes. We create template disc models exemplifying in…
Loss and fractionation of noble gas isotopes and moderately volatile elements from planetary embryos and early Venus, Earth and Mars
H. Lammer, M. Scherf, H. Kurokawa +12
Here we discuss the current state of knowledge on how atmospheric escape processes can fractionate noble gas isotopes and moderately volatile rock-forming elements that populate pr…
Structural transition and re-emergence of iron's total electron spin in (Mg,Fe)O at ultrahigh pressure
Han Hsu, Koichiro Umemoto
Fe-bearing MgO [(MgFe)O] is considered a major constituent of terrestrial exoplanets. Crystallizing in the B1 structure in the Earth's lower mantle, (MgFe)O…
