Spectrally blue hydrated parent body of asteroid (162173) Ryugu [PDF]
Both poles of asteroid Ryugu, the target of space mission Hayabusa2, preserve the least processed material by space weathering. Here, the authors show detection of 700 nm absorption band in the polar spectra of Ryugu, that allows to constrain the ...

Reconnecting groups of space debris to their parent body through proper elements [PDF]
Satellite collisions or fragmentations generate a huge number of space debris; over time, the fragments might get dispersed, making it difficult to associate them to the configuration at break-up.

Reduced and unstratified crust in CV chondrite parent body [PDF]
Meteorites may unlock the history of the early solar system. Here, the authors find, through Ca-Fe-rich secondary phases, that the distinction between reduced and oxidized CV chondrites is invalid; therefore, CV3 chondrites are asteroid fragments that ...

Correlated iron isotopes and silicon contents in aubrite metals reveal structure of their asteroidal parent body [PDF]
Iron isotopes record the physical parameters, such as temperature and redox conditions, during differentiation processes on rocky bodies. Here we report the results of a correlated investigation of iron isotope compositions and silicon contents of ...

Meteoritic Amino Acids: Diversity in Compositions Reflects Parent Body Histories [PDF]
The analysis of amino acids in meteorites dates back over 50 years; however, it is only in recent years that research has expanded beyond investigations of a narrow set of meteorite groups (exemplified by the Murchison meteorite) into meteorites of other

Parent-child resemblance in weight status and its correlates in the United States. [PDF]
Few studies have examined parent-child resemblance in body weight status using nationally representative data for the US.We analyzed Body Mass Index (BMI), weight status, and related correlates for 4,846 boys, 4,725 girls, and their parents based on US ...

COMPOSITIONAL HOMOGENEITY OF CM PARENT BODIES [PDF]
ABSTRACT CM chondrites are the most common type of hydrated meteorites, making up ∼1.5% of all falls. Whereas most CM chondrites experienced only low-temperature (∼0°C–120°C) aqueous alteration, the existence of a small fraction of CM chondrites that suffered both hydration and heating complicates our understanding of the early thermal ...

Cascade of Complications Following Carotid Body Tumor Excision [PDF]
Carotid body tumor excision can lead to various complications including vascular injury and pseudoaneurysm formation. Here we describe a case of carotid body tumor excision followed by series of complications including pseudoaneurysm formation, failure ...
