Low temperatures and high water/rock ratios in asteroid (101955) Bennu's history based on X‐ray powder diffraction of returned samples

Meteoritics &Planetary Science, Volume 61, Issue 6, Page 1077-1094, June 2026.
Abstract Samples returned by NASA's OSIRIS‐REx mission from the carbonaceous asteroid (101955) Bennu hold clues about conditions in the early solar system and the formation of planetary bodies. Initial investigation of Bennu samples found that they are rich in phyllosilicates and other secondary minerals formed during aqueous alteration of a larger ...

Potential of VIS‐IR imaging spectroscopy and SEM‐EDS and EMPA to map the mineralogical composition of NWA 7317 (CR6)

Meteoritics &Planetary Science, Volume 61, Issue 6, Page 1026-1044, June 2026.
Abstract Asteroid compositional analysis relies on comparing reflectance spectra with laboratory data from well‐characterized meteorites. To advance this comparison, we performed a comprehensive laboratory analysis on a slab of the Northwest Africa (NWA) 7317—CR6 carbonaceous chondrite.

Quantification of Crystal Chemistry of Fe‐Mg Carbonates by Raman Microspectroscopy and Near‐Infrared Remote Sensing

Earth and Space Science
On Earth, carbonate minerals are widely used as recorders of the geological environments in which they formed. Here, we present a method designed to retrieve the crystal chemistry of Fe‐Mg carbonate minerals using infrared remote sensing or Raman ...

Combustion and Pyrolysis EA‐IRMS Techniques to Determine the δ2H of Diamonds

Rapid Communications in Mass Spectrometry, Volume 40, Issue 10, 30 May 2026.
ABSTRACT Rationale Diamonds are generally considered to be metasomatic minerals originating from the Earth's mantle. They formed through the interaction of carbon‐bearing fluids or melts with the surrounding deep lithology. Most knowledge about the formation of diamonds comes from studying their mineral inclusions or stable isotopes.

On the Dynamics of a Synchronous Binary Asteroid System with Non-Uniform Mass Distribution

Mathematics
In this work, particle dynamics in a binary asteroid system is analyzed within the Circular Restricted Three-Body Problem (CRTBP) framework, assuming the largest body is treated as a mass point.
