An Analysis of the Recent Global Geologic History of Europa: Evidence for Clustered Resurfacing and a Lack of True Polar Wander

Journal of Geophysical Research: Planets, Volume 131, Issue 11, November 2026.
Abstract Global geologic mapping shows that Europa’s surface is made up of an array of features including extensive ridged plains, regions of broad disruption termed chaos terrain, quasi‐linear ridges that span thousands of km, and bands up to 60 km wide that extend for 100–1000s of km.

Sulfidation Reaction Mechanisms of Olivine and Diopside at Mercury's Reducing Conditions

Journal of Geophysical Research: Planets, Volume 131, Issue 11, November 2026.
Abstract The surface of Mercury contains elevated amounts of sulfur of up to 4 wt.%. Volcanic degassing of S from the interior of the planet could have initiated sulfidation reactions between the degassed S and surface materials in the planet's past, leading to the observed surface S enrichment.

Quiet Time Ionosphere‐Thermosphere Predictability During Sudden Stratospheric Warmings in TIE‐GCM

Space Weather, Volume 24, Issue 11, November 2026.
Abstract We investigate the predictability of the ionosphere‐thermosphere (IT) region during sudden stratospheric warmings (SSWs) by using subseasonal hindcasts in the Community Earth System Model, version 2 with the Whole Atmosphere Community Climate Model (CESM2 [WACCM6]) to force the lower boundary of the TIE‐GCM.

From spectroscopic abundances to evolutionary [α/Fe] in stellar models

Astronomy & Astrophysics
Context. Large-scale, high-resolution spectroscopic surveys map detailed chemical-abundance patterns for up to millions of stars. The richness of this information is used in a wide range of studies, from galactic archaeology and stellar populations to ...

Dynamical Solar Wind Forecasting Using In Situ Solar Wind Speed Observations

Space Weather, Volume 24, Issue 11, November 2026.
Abstract Accurate prediction of the ambient solar wind at Earth is a key requirement for space‐weather forecasting but is limited by uncertainties in coronal boundary conditions and, to a lesser extent, heliospheric transport. We present a quantitative assessment of a solar wind forecast that uses near‐Earth in situ solar wind observations to estimate ...

Neutron-captures in Low Mass Stars and the Early Solar System Record of Short-lived Radioactivities

EPJ Web of Conferences, 2017
Noticeable improvements were recently introduced in the modelling of n-capture nucleosynthesis in the advanced evolutionary stages of giant stars (Asymptotic Giant Branch, or AGB, stars).

Global Ionospheric Responses to Four X‐Class Solar Flares in November 2025

Space Weather, Volume 24, Issue 11, November 2026.
Abstract We investigate global ionospheric responses to four X‐class solar‐disk flares that occurred in November 2025 from the same solar active region, using multi‐instrument observations including GNSS, ionosonde, geomagnetic and GOES solar irradiance data. Pronounced dayside TEC enhancements are observed for three flares (#2 X1.2, #3 X5.1, and #4 X4.
