Spatial Distributions of Energetic Electrons and Energetic Ions in the Tail Reconnection Region: Cluster Observations and PIC Simulations

Geophysical Research Letters, Volume 53, Issue 1, 16 January 2026.
Abstract High‐energy particles are prevalent in space, and magnetic reconnection is one of the physical processes responsible for their generation. The heating and acceleration of ions and electrons typically occur respectively in the ion diffusion region and the electron diffusion region.

Exploring the Effects of Reduced Gravitational Field Impacts on Convective Heat Transfer: A Comprehensive Review

Heat Transfer, Volume 55, Issue 1, Page 764-774, January 2026.
ABSTRACT This review explores the impact of gravitational instability on convective heat transfer, integrating existing research results and theoretical models. Gravitational instability is vital in promoting or hindering convective actions in different systems, such as atmospheric events, ocean currents, and industrial processes.

Ground-based Characterization of Hayabusa2 Mission Target Asteroid 162173 Ryugu: Constraining Mineralogical Composition in Preparation for Spacecraft Operations

, 2017
Asteroids that are targets of spacecraft missions are interesting because they present us with an opportunity to validate ground-based spectral observations. One such object is near-Earth asteroid (NEA) (162173) Ryugu, which is the target of the Japanese

Adsorption of Helium on Cationic or Anionic Tetracene and Pentacene

Small Structures, Volume 7, Issue 1, January 2026.
How does the arrangement of helium atoms that are adsorbed on tetracene or pentacene ions change with increasing coverage? When does the adsorption layer change from 1D to 2D, and to 3D? Is the transition abrupt? Are the helium atoms localized? Is the arrangement the same for cations and anions? What changes as the acene grows in length?

Prediction of transits of solar system objects in Kepler/K2 images: An extension of the Virtual Observatory service SkyBoT

, 2016
All the fields of the extended space mission Kepler/K2 are located within the ecliptic. Many solar system objects thus cross the K2 stellar masks on a regular basis.

Baseline Climatology of Gravity Waves From ∼30 to ∼70 km Established With Lidar Observations Over a Decade at McMurdo (77.84°S, 166.67°E), Antarctica: Implications for Vertical Wave Evolution

Earth and Space Science, Volume 13, Issue 1, January 2026.
Abstract Lidar observations of atmospheric gravity waves (GWs) have been made spanning 14 years above McMurdo Station, Antarctica. Using these extensive observations and interleaved data processing techniques which enable bias‐free/noise‐floor‐free estimation of GW parameters, this study forms seasonal baselines for GW potential energy densities (Epm ...

Effect of Land Cover Type on 3D Deformation Recovery From Synthetically Deformed High Resolution Satellite Optical Imagery

Earth and Space Science, Volume 13, Issue 1, January 2026.
Abstract The limits of detection for earthquake surface deformation in the spatial domain have improved with advances in remote sensing imagery data availability, resolution, and analysis. Sub‐pixel correlation and digital elevation model (DEM) differencing from sub‐meter, earthquake‐spanning satellite optical imagery has enhanced surface rupture ...

Deep‐Ultraviolet (DUV) Raman and Fluorescence of Perchlorates and Chlorates: Implications for the Detection of Oxychlorines by the SHERLOC Instrument in Jezero Crater, Mars

Earth and Space Science, Volume 13, Issue 1, January 2026.
Abstract Oxychlorines (i.e., perchlorates (ClO4−) and chlorates (ClO3−)) have been detected by several landed missions on Mars at various locations. These missions have provided crucial information about the geographic distribution and abundances of oxychlorines on Mars but have not definitively identified the cation and anion type of in situ, solid ...
