The N ano SIMS ion probe is a new‐generation SIMS instrument, characterised by superior
spatial resolution, high sensitivity and multi‐collection capability. Isotope studies of certain …

Pristine stardust grains from the interstellar gas and dust cloud from which our Solar System
formed some 4.57 billion years ago are present in small quantities in primitive Solar System …

Interstellar dust (ISD) is the condensed phase of the interstellar medium. In situ data from the
Cosmic Dust Analyzer on board the Cassini spacecraft reveal that the Saturnian system is …

From their birth as condensates in the outflows of oxygen-rich evolved stars, processing in
interstellar space, and incorporation into disks around new stars, amorphous silicates …

We report the identification of presolar silicates (∼ 177 ppm), presolar oxides (∼ 11 ppm),
and one presolar SiO 2 grain in the Allan Hills (ALHA) 77307 chondrite. Three grains having …

Here we report the relative degrees of thermal metamorphism for five Antarctic Ornans-like
carbonaceous (CO) chondrites, including Dominion Range (DOM) 08006, as determined …

Close to a thousand presolar silicate grains have been identified since their initial discovery
in interplanetary dust particles (IDPs) just over ten years ago. Studies have shown that …

We have investigated the fine‐grained matrix of the least‐altered unequilibrated ordinary
chondrite (UOC) Semarkona (LL3. 00) using different electron microscope techniques …

Amorphous silicates in meteoritic samples are significant as potential surviving interstellar
dust from the formation of the Solar System. Amorphous silicate-rich grains called GEMS …

A comprehensive study of the organic chemistry and mineralogy of an ultracarbonaceous
micrometeorite (UCAMM D05IB80) collected from near the Dome Fuji Station, Antarctica …
