Covering: 1950s to the present day The carbonaceous chondrite meteorites are fragments of
asteroids that have remained relatively unprocessed since the formation of the solar system …

▪ Abstract Primitive meteorites contain grains of stardust that originated from stellar outflows
and supernova ejecta prior to the formation of the Solar System. The study of these grains in …

Direct links between carbonaceous chondrites and their parent bodies in the solar system
are rare. The Winchcombe meteorite is the most accurately recorded carbonaceous …

The Genesis mission sampled solar wind ions to document the elemental and isotopic
compositions of the Sun and, by inference, of the protosolar nebula. Nitrogen was a key …

This paper reports the first reliable quantitative determination of the thermal metamorphism
grade of a series of nine CV3 chondrites: Allende, Axtell, Bali, Mokoia, Grosnaja, Efremovka …

▪ Abstract Meteorites and interplanetary dust particles contain presolar stardust grains: solid
samples of stars that can be studied in the laboratory. The stellar origin of the grains is …

Diamond is a remarkable mineral and has been long recognized for its unusual physical
and chemical properties: robust and widespread in industry, yet regally adorned. This …

This review provides an introduction to presolar grains–preserved stardust from the
interstellar molecular cloud from which our solar system formed–found in primitive …

Grains of dust that pre-date the Sun provide insights into their formation around other stars
and into the early evolution of the Solar System,,,. Nanodiamonds recovered from …

The N and C abundances and isotopic compositions of acid‐insoluble carbonaceous
material in thirteen primitive chondrites (five unequilibrated ordinary chondrites, three CM …
