Evidence for widespread hydrated minerals on asteroid (101955) Bennu
Evidence for abundant hydrated minerals on the surface of near-Earth asteroid Bennu is revealed in the form of a near-infrared absorption near 2.7 µm and thermal infrared spectral features that are most similar to those of aqueously altered CM-type carbonaceous chondrites.
Large enantiomeric excesses in primitive meteorites and the diverse effects of water in cosmochemical evolution
It is found that several CR compounds are fully represented in stones with no or minimal water exposure indicating a formation that, if solar, preceded parent body processes, and the most pristine CRs also revealed natal enantiomeric excesses of up to 60%, much larger than ever recorded.
The formation and alteration of the Renazzo‐like carbonaceous chondrites III: Toward understanding the genesis of ferromagnesian chondrules
To better understand the formation conditions of ferromagnesian chondrules from the Renazzo‐like carbonaceous (CR) chondrites, a systematic study of 210 chondrules from 15 CR chondrites was
Shape of (101955) Bennu indicative of a rubble pile with internal stiffness
The shape model indicates that near-Earth asteroid Bennu formed by reaccumulation and underwent past periods of fast spin, which led to its current shape, similar to other top-shaped asteroids.
