Coupled Space Weathering: Nanophase Iron Formation by Micrometeoroid Impact and Solar Wind Sputtering

Geophysical Research Letters, Volume 53, Issue 7, 16 April 2026.
Abstract Understanding the interplay between micrometeoroid impacts and solar wind irradiation is crucial for interpreting lunar surface evolution. Using reactive molecular dynamics simulations and surface binding energy (SBE) analyses, this study investigates the coupled effects of these two dominant space weathering processes on lunar regolith ...

ORBITAL PERTURBATIONS OF THE GALILEAN SATELLITES DURING PLANETARY ENCOUNTERS [PDF]

, 2014
The Nice model of the dynamical instability and migration of the giant planets can explain many properties of the present solar system, and can be used to constrain its early architecture.

Crater Morphometry on Callisto

The Planetary Science Journal
Impact crater formation is affected by the physical properties of planetary crusts, allowing comparison of crater dimensions to serve as a proxy for comparing the crustal properties of different planetary bodies.

Engineering Topological Phases with a Traveling‐Wave Spacetime Modulation

Laser &Photonics Reviews, Volume 20, Issue 7, 6 April 2026.
Time‐varying systems have garnered considerable attention due to their unique potential in manipulating electromagnetic waves. Here, a novel class of topological spacetime crystals with a traveling‐wave modulation is introduced. By manipulating material anisotropy, one can engineer light angular momentum and non‐trivial topological phases characterized

The formation of the Galilean moons and Titan in the Grand Tack scenario

, 2015
In the Grand Tack (GT) scenario for the young solar system, Jupiter formed beyond 3.5 AU from the Sun and migrated as close as 1.5 AU until it encountered an orbital resonance with Saturn.

Delivery of Dust Particles from Protoplanetary Disks onto Circumplanetary Disks of Giant Planets

The Astrophysical Journal
The principal regular satellites of gas giants are thought to be formed by the accumulation of solid materials in circumplanetary disks (CPDs). While there has been significant progress in the study of satellite formation in CPDs, details of the supply ...

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 ...

Hitchhiker's Guide to the Swampland: The Cosmologist's Handbook to the String‐Theoretical Swampland Programme

Fortschritte der Physik, Volume 74, Issue 4, April 2026.
Abstract String theory has strong implications for cosmology, implying the absence of a cosmological constant, ruling out single‐field slow‐roll inflation, and that black holes decay. The origins of these statements are elucidated within the string‐theoretical swampland programme.

A Gas-poor Planetesimal Capture Model for the Formation of Giant Planet Satellite Systems

, 2005
Assuming that an unknown mechanism (e.g., gas turbulence) removes most of the subnebula gas disk in a timescale shorter than that for satellite formation, we develop a model for the formation of regular (and possibly at least some of the irregular ...

Modeling the Jovian subnebula: I - Thermodynamical conditions and migration of proto-satellites [PDF]

, 2005
We have developed an evolutionary turbulent model of the Jovian subnebula consistent with the extended core accretion formation models of Jupiter described by Alibert et al. (2005b) and derived from Alibert et al. (2004,2005a).
