The effects of pressure on immiscibility in metallic, core‐forming liquids: Implications for protoplanetary differentiation

Meteoritics &Planetary Science, EarlyView.
Abstract Mechanisms for metal core formation in rocky planetesimals and planetary embryos remain poorly constrained, in part due to complexities arising from immiscibility in core‐forming liquids at low pressures. To assess the pressure dependence of immiscibility and its role in protoplanetary differentiation, we performed experiments at 3 and 5 GPa ...

Heidegger and Levinas on the phenomenology of the hand: Between work and gesture

The Southern Journal of Philosophy, EarlyView.
Abstract This article explores how Heidegger and Levinas develop distinct phenomenological accounts of the hand. Both thinkers refuse to treat the hand as merely an anatomical organ, instead viewing it as an essential dimension of human existence. Yet their interpretations diverge sharply. In the first section, I show how Heidegger grounds the function

Segmented dike intrusion linked to multi-level magma storage during and before the 2025 eruption at Erta Ale (East Africa)

Frontiers in Earth Science
IntroductionDike intrusions can assist continental rifting and plate divergence. However, our understanding of the magma dynamics during diking and the architecture of the magma storage that feeds dikes are still limited by temporally and spatially ...

Numerical solution of a non-linear conservation law applicable to the interior dynamics of partially molten planets

, 2017
The energy balance of a partially molten rocky planet can be expressed as a non-linear diffusion equation using mixing length theory to quantify heat transport by both convection and mixing of the melt and solid phases.

Effect of Re-impacting Debris on the Solidification of the Lunar Magma Ocean

, 2018
Anorthosites that comprise the bulk of the lunar crust are believed to have formed during solidification of a Lunar Magma Ocean (LMO) in which these rocks would have floated to the surface.

Quantifying Microstructural Evolution in Moving Magma

Frontiers in Earth Science, 2020
Many of the grand challenges in volcanic and magmatic research are focused on understanding the dynamics of highly heterogeneous systems and the critical conditions that enable magmas to move or eruptions to initiate.
