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

open access: yesGeophysical 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 ...

Unobservable mutual events of the Galilean satellites

open access: yes, 2002
Mutual eclipses and occultations of the Galilean satellites of Jupiter which will occur in 2002–2003 were predicted independently by J.-E. Arlot and by K.

Ion Implantation and Chemical Cycles in the Icy Galilean Satellites [PDF]

open access: yes, 2023
An essential requisite for the appearance and permanence of life on Earth is the onset of a continuous “cycling” of some key atoms and molecules. Cycling of elements probably also occurs on other objects and is driven by biological or a-biological ...

Formation of Water-rich Giant Planet Satellites at Decretion Disk Ice Lines

open access: yesThe Planetary Science Journal
The volatile budgets of giant planet satellites are critical to unraveling the origin of their building blocks within the circumplanetary disks that hosted them.

Engineering Topological Phases with a Traveling‐Wave Spacetime Modulation

open access: yesLaser &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

On the Migration of the Galilean Satellites [PDF]

open access: yes, 2013
The migration of the Galilean satellites during formation due to interactions with the circumjovian disk is studied. In the gas-starved disk model proposed by Canup & Ward (2002, 2006), the Galilean satellites are the last generation of satellites ...

Coordinates of features on the Galilean satellites

open access: yes, 1980
The coordinate systems of each of the Galilean satellites are defined and coordinates of features seen in the Voyager pictures of these satellites are presented.

The Stability of a Dense Crust Situated on Small Bodies

open access: yesThe 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 ...

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

open access: yesFortschritte 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.

Predictions of the mutual events of the Galilean satellites of Jupiter occurring in 2009–2010

open access: yes, 2007
Aims. Mutual occultations and eclipses of the Galilean satellites of Jupiter will occur in 2009–2010. This paper provides predictions of these events as well as useful information for their observations.
