Silicate–sulfide interaction within quenched melts of space weathered Ryugu grains
Meteoritics &Planetary Science, EarlyView.Abstract The first few microns of the surface of airless bodies are subject to severe changes due to the harsh environment of space, known as space weathering. The Hayabusa2 sample return mission from the asteroid Ryugu provides the first opportunity to study these effects on a carbonaceous and hydrated body.

Modeling Galaxies in the Early Universe with Supernova Dust Attenuation
The Astrophysical Journal LettersSupernovae (SNe) may be the dominant channel by which dust grains accumulate in galaxies during the first Gyr of cosmic time as formation channels important for lower-redshift galaxies, e.g., asymptotic giant branch stars and grain growth, may not have ...

Meteoritics &Planetary Science, EarlyView.Abstract Meteorite collection inventories show that many related meteorite groups have very different numerical abundances (e.g., lunar versus Martian meteorites; Eagle Station pallasites versus main‐group pallasites; eucrites versus diogenites; ungrouped Antarctic irons versus ungrouped non‐Antarctic irons; carbonaceous chondrite‐related (CC) iron ...

The mineralogy of cosmic dust: astromineralogy
European Journal of Mineralogy, 2007 Stardust is newly-formed in the ejected shells of gas that surround stars towards the end of their lives. Observations of the thermal emission from this dust, which is at relatively low temperatures ( T = 50–200 K), in the circumstellar shells around these stars indicate that the dust consists of both amorphous and crystalline materials.

Meteoritics &Planetary Science, EarlyView.Abstract We report the discovery of (Al,Cu)‐bearing metallic alloys in two micrometeorites found in the Project Stardust collection gathered from urban rooftop environments in Norway. Most of the alloys are the same as those found in the Khatyrka meteorite and other micrometeorites, though one has a composition that has not been reported previously ...

ISM spectrum by cosmic dust? [PDF]
Proceedings of the International Astronomical Union, 2008 AbstractThe interstellar medium (ISM) spectrum is usually explained by the response of dust particles (DPs) to the absorption of ultraviolet (UV) and visible (VIS) photons from nearby stars. With regard to the unidentified infrared (UIR) bands, the DPs are thought heated by UV and VIS photons to about 100 K thereby exciting the polycyclic aromatic ...

Topics in Cognitive Science, EarlyView.Abstract This manuscript documents a systematic ethnomycological analysis of ethnographic archives. Focusing on texts describing human–fungi interactions, I conduct a global, cross‐cultural review of mushroom use, covering 193 societies worldwide. The study reveals diverse mushroom‐related cultural practices, emphasizing the significance of fungi ...

Mining an Anthropocene in Japan: On the making and work of geological imaginaries
Transactions of the Institute of British Geographers, EarlyView.Short Abstract This article addresses how the lithic and the drift might be reworked as an Anthropocene material outside of a chronostratigraphy. Revisiting the finding of a floating fern fossil at the Hashima mine, we delve into a complex array of Geological imaginaries, and undertake our own speculative work.
