Geological Mapping and Structural Analysis of the Western Half of the Eminescu Quadrangle (H09), Mercury

Journal of Geophysical Research: Planets, Volume 131, Issue 6, June 2026.
Abstract We present the results of the first geological mapping of the western half of the Eminescu Quadrangle (H09) on Mercury. Multiple data sets from the NASA MESSENGER Mercury Dual Imaging System instrument were used to produce a geological map covering the area between 72°E and 108°E longitude and 22.5°N and 22.5°S latitude.

LBT/LUCIFER near-infrared spectroscopy of PV Cephei. An outbursting young stellar object with an asymmetric jet

, 2013
J.D. Ilee acknowledges funding from the European Union FP7−2011 under grant agreement no. 284405.Context. Young stellar objects (YSOs) occasionally experience enhanced accretion events, the nature of which is still poorly understood.

Fluid‐Driven Cohesive Strengthening: Critical Role of Reaction Kinetics as the Determinant for Frictional Stability

AGU Advances, Volume 7, Issue 3, June 2026.
Abstract Following an earthquake, faults lock and regain strength via a combination of healing mechanisms that include pressure solution, contact growth, and cementation. Fault healing dictates strength recovery during the seismic cycle and is therefore a key factor controlling earthquake recurrence intervals, stress drop, and other source properties ...

Infrared Colors of Small Serendipitously Found Asteroids in the UKIRT Hemisphere Survey

The Astronomical Journal
The UKIRT Hemisphere Survey covers the northern sky in the infrared from 0° to 60° decl. Current data releases include both J and K bands, with H -band data forthcoming. Here, we present a novel pipeline to recover asteroids from this survey data.

Mapping Quartz and Feldspar Areal Abundance and Grain Sizes Using Integrated VTIR Data

AGU Advances, Volume 7, Issue 3, June 2026.
Abstract Mineral dust is sourced from arid regions around the globe, and its composition impacts regional and global environments by affecting radiation balance, cloud formation, nutrient deposition, and snowmelt. As such, mineral dust plays a key role in Earth's energy and biogeochemical budgets.
