The geomorphology, color, and thermal properties of Ryugu: Implications for parent-body processes. [PDF]

Science, 2019
Hayabusa2 at the asteroid Ryugu Asteroids fall to Earth in the form of meteorites, but these provide little information about their origins. The Japanese mission Hayabusa2 is designed to collect samples directly from the surface of an asteroid and return

An extraterrestrial trigger for the mid-Ordovician ice age: Dust from the breakup of the L-chondrite parent body. [PDF]

Sci Adv, 2019
The disruption of a 150-km large asteroid filled the inner solar system with dust that cooled Earth and caused faunal turnovers. The breakup of the L-chondrite parent body in the asteroid belt 466 million years (Ma) ago still delivers almost a third of ...

Meteorite Parent Body Aqueous Alteration Simulations of Interstellar Residue Analogs [PDF]

ACS Earth and Space Chemistry, 2023
Some families of carbonaceous chondrites are rich in prebiotic organics that may have contributed to the origin of life on Earth and elsewhere. However, the formation and chemical evolution of complex soluble organic molecules from interstellar ...

Unique achondrite Northwest Africa 11042: Exploring the melting and breakup of the L chondrite parent body [PDF]

Meteoritics and Planetary Science, 2020
Northwest Africa (NWA) 11042 is a heavily shocked achondrite with medium‐grained cumulate textures. Its olivine and pyroxene compositions, oxygen isotopic composition, and chromium isotopic composition are consistent with L chondrites.

Thermal history modelling of the L chondrite parent body [PDF]

Astronomy & Astrophysics, 2019
Context.The cooling history of individual meteorites can be reconstructed if closure temperatures and closure ages of different radioisotopic chronometers are available for a couple of meteorites.

Jadeite in Chelyabinsk meteorite and the nature of an impact event on its parent body. [PDF]

Sci Rep, 2014
The Chelyabinsk asteroid impact is the second largest asteroid airburst in our recorded history. To prepare for a potential threat from asteroid impacts, it is important to understand the nature and formational history of Near-Earth Objects (NEOs) like ...

Systematic electronic structure in the cuprate parent state from quantum many-body simulations [PDF]

Science, 2021
The quantitative description of correlated electron materials remains a modern computational challenge. We demonstrate a numerical strategy to simulate correlated materials at the fully ab initio level beyond the solution of effective low-energy models ...

Incremental melting in the ureilite parent body: Initial composition, melting temperatures, and melt compositions

Meteoritics and Planetary Science, 2020
Ureilites are carbon‐rich ultramafic achondrites that have been heated above the silicate solidus, do not contain plagioclase, and represent the melting residues of an unknown planetesimal (i.e., the ureilite parent body, UPB). Melting residues identical

Parental Determinants of Neonatal Body Composition [PDF]

The Journal of Clinical Endocrinology & Metabolism, 2007
The prevalence of both childhood and adult obesity is rising in the developed world, and there is increasing interest in its underlying causes. A number of studies suggest a positive relationship between birth weight and childhood body mass index, but less is known about specific prenatal environmental influences on more direct measures of obesity.
