Not just gas: How solids-driven torques shaped the migration of the Galilean moons

Astronomy & Astrophysics
Context. A crucial aspect of formation models for the Galilean moons of Jupiter is that the objects survive rapid inward orbital migration. Aims. The primary aim of this study is to investigate the orbital migration of the Galilean moons by incorporating

A Geoscientific Review on CO and CO₂ Ices in the Outer Solar System

Geosciences, 2022
Ground-based telescopes and space exploration have provided outstanding observations of the complexity of icy planetary surfaces. This work presents our review of the varying nature of carbon dioxide (CO2) and carbon monoxide (CO) ices from the cold ...

Reconstructing Europa's Atmosphere From H2+ ${\mathbf{H}}_{\mathbf{2}}^{+}$ Pickup Ions Detected During the Juno PJ45 Flyby

Journal of Geophysical Research: Planets, Volume 131, Issue 8, August 2026.
Abstract We use a suite of single‐species (H2 ${\mathrm{H}}_{2}$) and multispecies (H2+O2+H+O ${\mathrm{H}}_{2}+{\mathrm{O}}_{2}+\mathrm{H}+\mathrm{O}$) Direct Simulation Monte Carlo models of Europa's atmosphere to interpret the H2+ ${\mathrm{H}}_{2}^{+}$ pickup ions detected by Juno at distances beyond 2 $2$ Europa radii RE $\left({R}_{E}\right ...

Landfall Reorganizes Eyewall Boundary Layer Transport and Scale Coupling in Typhoon Hato (2017)

Geophysical Research Letters, Volume 53, Issue 13, 16 July 2026.
Abstract Landfall reorganizes the tropical cyclone eyewall boundary layer (BL) through elevated surface roughness and reduced enthalpy fluxes. Using a 100‐m resolution nested large‐eddy simulation of Typhoon Hato (2017), we compare eyewall BL structures before and during landfall.

The Stability of a Dense Crust Situated on Small Bodies

The Planetary Science Journal
Small planetary bodies in the solar system, including Io, Ganymede, and Callisto, may have a crust denser than their underlying mantle. Despite the inherent gravitational instability of such structures, we show that the growth timescale of the Rayleigh ...

Interactions of Sublimated Frost With Volcanic Plumes: Modeling Io's SO2 Atmosphere Using the DSMC Method

Journal of Geophysical Research: Planets, Volume 131, Issue 7, July 2026.
Abstract Io's tenuous atmosphere consists primarily of sulfur dioxide (SO2 ${\text{SO}}_{2}$) with observed column densities of approximately 1016−1017 $1{0}^{16}-1{0}^{17}$ cm−2 ${\text{cm}}^{-2}$. However, it remains uncertain whether the sublimation of SO2 ${\text{SO}}_{2}$ surface frost or volcanic outgassing is the primary source of the SO2 ...

The Lense–Thirring Effect on the Galilean Moons of Jupiter

Universe, 2023
The perspectives of detecting the general relativistic gravitomagnetic Lense–Thirring effect on the orbits of the Galilean moons of Jupiter induced by the angular momentum S of the latter are preliminarily investigated.

Deterministic Theories

Philosophy and Phenomenological Research, Volume 113, Issue 1, Page 134-152, July 2026.
ABSTRACT Determinism is (roughly) the thesis that the past determines the future. But efforts to define it precisely have exposed deep methodological disagreements. Standard possible‐worlds formulations of determinism presuppose an “agreement” relation between worlds, but this relation can be understood in multiple ways, none of which is particularly ...

Onboard Science Instrument Autonomy for the Detection of Microscopy Biosignatures on the Ocean Worlds Life Surveyor

The Planetary Science Journal
The quest to find extraterrestrial life is a critical scientific endeavor with civilization-level implications. Icy moons in our solar system are promising targets for exploration because their liquid oceans make them potential habitats ...
