Zinc isotope anomalies in primitive meteorites identify the outer solar system as an important source of Earth's volatile inventory
The source of and timing of delivery of the volatile elements to Earth is a question that is
fundamental to understanding how our planet evolved. Here, we show that primitive …

The 21 μm and 30 μm emission features in carbon-rich objects
K Volk, GC Sloan, KE Kraemer - Astrophysics and Space Science, 2020 - Springer
We review the observational properties and possible carriers of the 21 and 30 μm features
seen in the spectra of evolved carbon-rich objects. The 30 μm feature is generally taken to …

An evolutionary system of mineralogy. Part I: Stellar mineralogy (> 13 to 4.6 Ga)
RM Hazen, SM Morison - American Mineralogist, 2020 - degruyter.com
Minerals preserve records of the physical, chemical, and biological histories of their origins
and subsequent alteration, and thus provide a vivid narrative of the evolution of Earth and …

On presolar stardust grains from CO classical novae
Abstract About 30%–40% of classical novae produce dust 20–100 days after the outburst,
but no presolar stardust grains from classical novae have been unambiguously identified …

Proton ingestion in asymptotic giant branch stars as a possible explanation for J-type stars and AB2 grains
Context. J-type stars are a subclass of carbon stars that are generally Li-rich, not enriched in
s-elements, and have low 12 C/13 C ratios. They were suggested to be the manufacturers of …
