Meteoritics &Planetary Science, EarlyView.Abstract This study investigates the spatial distribution and spectral characteristics of the broad hydration feature near 3 μm across the surface of asteroid (101955) Bennu using OVIRS (OSIRIS‐REx Visible and InfraRed Spectrometer) data. We analyzed multiple global OVIRS data sets obtained at different times throughout the Bennu day, revealing ...

Thermal history, collisional history, and structure of the CK‐chondrite parent body
Meteoritics &Planetary Science, EarlyView.Abstract Major chondrite groups (H, L, LL, R, EH, EL, CK) with some members of petrologic type 5 and 6 also have some members of types 3 and 4; they do not have members of type 1 or 2. Their parent bodies had onion‐shell structures and were internally heated by the decay of 26Al.

Earth, Planets and Space, 2023 One of the outstanding questions in planetary science is to determine how the fundamental mechanical and physical properties of materials determine the thermal evolution of asteroids, and which properties have the greatest influence.

Chondrule size averaging in two and three dimensions
Meteoritics &Planetary Science, EarlyView.Abstract Chondrule sizes are an important discriminant of chondrite groups and chondrule formation theories. Yet most studies report 2‐D sizes without attempting the somewhat tedious corrections to 3‐D proposed in the past literature. I show here that 3‐D size averages can be simply calculated directly from 2‐D averages of appropriate powers of sizes ...

Mean atomic weight of Vicência LL3.2 chondrite [PDF]
, 2018 Mean atomic weight Amean of Vicência (LL3.2 S1W0, fall 2013) ordinary chondrite has been calculated using literature data (Keil et al. 2015) on chemical composition of the meteorite and using relationships: between mean atomic weight and Fe/Si atomic ...

Ferropseudobrookite-silica mineral-albite-chondrule in the ALH-77015 chondrite (L3) [PDF]
, 1981 P(論文)Ferropseudobrookite-silica mineral-albite-chondrule was found in an unequilibraed (L3) chondrite (ALH-77015). This is the first finding of ferropseudobrookite in chondrite. The ferropseudobrookite exhibits a weakly zonal structure.

Thermal history of an amoeboid olivine aggregate in the early solar nebula
Meteoritics &Planetary Science, EarlyView.Abstract Carbonaceous chondrites commonly contain amoeboid olivine aggregates (AOAs). Here, we investigated an AOA in the CR chondrite Y‐793261. This AOA contains an unstable assemblage of forsterite and quartz. We found a rare occurrence of enstatite and quantitatively discuss its formation process.
