Journal of Geophysical Research: Planets, Volume 131, Issue 3, March 2026.Abstract Recently, possible exceptionally young mare volcanic glass beads were discovered in Chang'e‐5 (CE‐5) samples. Isotopic dating suggests an age of approximately 120 Ma, presenting new challenges to existing lunar thermal evolution models. Thus, our research focuses on the source region of Rima Mairan, a branch of Rima Sharp, and its surrounding ...

, 2010 To account for the non-thermal emission from the classical nova V2491 Cygni, we perform a series of numerical calculations of radiative transfer of \gamma-ray photons from the radioactive isotope $^{22}$Na in the matter ejected from a white dwarf.

Exploring the Interior Structure of (16) Psyche Through Basin‐Scale Collisions
Journal of Geophysical Research: Planets, Volume 131, Issue 3, March 2026.Abstract Asteroid (16) Psyche, the largest member of the M/X‐type asteroids, may be the leftover core of a differentiated planetesimal. As such (16) Psyche will be explored in detail by NASA's discovery‐class Psyche mission in 2029. This will be the first mission to orbit a metal‐rich asteroid, or any asteroid in the 100–500 km size range.

Ancient eruptions of Eta Carinae: A tale written in proper motions
, 2016 We analyze eight epochs of Hubble Space Telescope H$\alpha$+[N II] imaging of Eta Carinae's outer ejecta. Proper motions of nearly 800 knots reveal that the detected ejecta are divided into three apparent age groups, dating to around 1250 A.D., to around

Journal of Geophysical Research: Planets, Volume 131, Issue 3, March 2026.Abstract The flux of solar system meteoroids is dominated by objects less than 1 mm in diameter whose impact effects play a major role in the space weathering of airless body surfaces. These effects remain poorly characterized with respect to their dependence on the range of impact speeds for meteoroids across the inner solar system.

Asymmetric Crater Relaxation on an Ice‐Rich Ceres Driven by Insolation
Journal of Geophysical Research: Planets, Volume 131, Issue 3, March 2026.Abstract Ceres has a high ice content within its crust and is the closest dwarf planet to the sun. The resultant high insolation levels at Ceres' surface (in comparison to the outer solar system) leads to high variations in surface temperature, which is dependent on both latitude and orientation of the slope (i.e., equatorward‐ or poleward‐facing).

r-process Heating Feedback on Disk Outflows from Neutron Star Mergers
The Astrophysical JournalNeutron star mergers produce r -process elements, with yields that are sensitive to the kinematic and thermodynamic properties of the ejecta. These ejecta properties are potentially affected by dynamically important feedback from r -process heating ...

Effect of Target Properties on Regolith Production
Remote SensingBased on the measurements of regolith thicknesses on the lunar maria (basalts), the lunar regolith was determined to have accumulated at a rate of about 1 m/Gyr since the era of the late heavy bombardment.

Ejecta velocities in twice-shocked liquid metals under extreme conditions: A hydrodynamic approach
Matter and Radiation at Extremes, 2019 We apply a hydrodynamic approach to analyze ejecta emanating from doubly shocked liquid metals. In particular, we are interested in characterizing ejecta velocities in such situations by treating the problem as a limiting case of the ...
