Barchans Interacting With Dune‐Size Obstacles: Details of the Fluid Flow and Motion of Grains

Journal of Geophysical Research: Earth Surface, Volume 130, Issue 6, June 2025.
Abstract We investigate details of the interaction of subaqueous barchans with dune‐size obstacles by carrying out numerical simulations where the fluid is solved at the grain scale and the motions of individual grains are computed at all time steps. With the outputs, we analyze the disturbances of the fluid flow, the trajectories of grains, and the ...

CO2: Adsorption on palagonite and the Martian regolith [PDF]

Possible scenarios for the evolution of the Martian climate are discussed. In the interest of determining an upper limit on the absorptive capacity of the Martian regolith, researchers examined the results of Fanale and Cannon (1971, 1974) for CO2 ...

Evidence for phosphate metasomatism in an olivine‐rich achondrites

Meteoritics &Planetary Science, Volume 60, Issue 6, Page 1302-1317, June 2025.
Abstract Brachinites, brachinite‐like achondrites (BLA), and other similar primitive achondrites offer important constraints on differentiation processes of the earliest formed planetesimals, as they quenched amidst early differentiation processes on their parent body. Geochemical data for all major mineral phases in two previously poorly characterized

Revealing the CME Impact on the Martian Nightside Ionosphere Based on MAVEN and Tianwen-1 Observations

The Astrophysical Journal
Due to the absence of an Earth-like dipole magnetic field, the impact of coronal mass ejections (CMEs) on the Martian nightside ionosphere differs from that on Earth and is still not well understood.

Possible dynamical mechanisms for the Martian polar warming phenomenon [PDF]

The research performed under NASA contract NAGW-727 falls into three major categories, i.e., dynamical modeling of the Martian polar warming phenomenon, studies of dust and water transport associated with a Martian polar warming, and studies of the ...

A complete inventory of institutional and public meteorite collections in Switzerland

Meteoritics &Planetary Science, Volume 60, Issue 6, Page 1384-1410, June 2025.
Abstract Museums and universities are important for collecting, maintaining, and curating meteorites. To make specimens known and available for research, inventorying and optimal curation are important. However, not all meteorite collections are well curated, especially in smaller institutions.
