Meteoritics &Planetary Science, EarlyView.Abstract Regolith samples from the carbonaceous asteroid Bennu were stowed and delivered to Earth in the OSIRIS‐REx spacecraft's Sample Return Capsule (SRC). We applied multiple analytical techniques to study the components of the post‐flight SRC, with a focus on assessing the conditions and any contaminants to which the Bennu samples were exposed ...

Xenoliths in meteorites: Insights into the dynamics of material exchange between asteroids
Meteoritics &Planetary Science, EarlyView.Abstract A minor fraction of meteorites contains xenoliths, that is, clasts that were formed on a different parent body than that of the host lithology. The occurrence of xenoliths is direct evidence for the exchange of material between asteroids, including exchanges between asteroids from the carbonaceous (CC) and non‐carbonaceous (NC) reservoirs ...

Synthesis of organic matter by stars and its effect on the origin of life on earth [PDF]
, 2011 The last 10(5) years of stellar evolution represents the most active period of synthesis of organic compounds in a star’s life. Over 60 gas-phase molecules, including rings, radicals, and molecular ions have been identified by millimeter-wave and ...

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.

Light Elements in the Universe
Frontiers in Astronomy and Space Sciences, 2021 Due to their production sites, as well as to how they are processed and destroyed in stars, the light elements are excellent tools to investigate a number of crucial issues in modern astrophysics: from stellar structure and non-standard processes at work

Meteoritics &Planetary Science, EarlyView.Abstract Apatite is often the most rare earth element (REE)‐enriched mineral in chondritic meteorites. REE enrichment and fractionation levels in apatite grains can give insight into the aqueous fluids in which they formed and the conditions prevailing within the host body. In this study, we applied synchrotron X‐ray fluorescence (SXRF) spectroscopy to

Neutrino treatment in multidimensional astrophysical simulations : a new spectral scheme [PDF]
, 2014 Neutrinos play a central role in modern physics and astrophysics. Their extremely weak interaction rate with baryons and other leptons makes their detection on the Earth difficult and challenging.
