▪ 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 indicated by enormous isotopic ratio variations compared with Solar System materials, explainable only by nuclear reactions occurring in stars. Known presolar phases include diamond, SiC, graphite, Si3N4, Al2O3, MgAl2O4, CaAl12O19, TiO2, Mg(Cr,Al)2O4, and most recently, silicates. Subgrains of refractory…

Abstract A small fraction of primitive meteorites and interplanetary dust particles (IDPs) consists of grains of presolar stardust. These grains have extremely unusual isotopic compositions, relative
1.4 – Presolar Grains
Primitive meteorites contain tiny grains that condensed in the outflows of late-type stars and in supernova ejecta. These samples of stardust, older than the Sun and thus called presolar grains, were
ISOCHRONS IN PRESOLAR GRAPHITE GRAINS FROM ORGUEIL
Primitive meteorites contain tiny dust grains that condensed in stellar outflows and explosions. These stardust grains can be extracted from their host meteorites and studied in detail in the
Presolar Stardust In The Solar System: Recent Advances for Nuclear Astrophysics
Grains of presolar stardust are identified in extraterrestrial materials on the basis of highly anomalous isotopic compositions. These compositions reflect those of the stellar gases from which they
CONSTRAINTS ON HETEROGENEOUS GALACTIC CHEMICAL EVOLUTION FROM METEORITIC STARDUST
Meteorites contain presolar grains that formed in stars prior to solar system formation and preserve a record of stellar and galactic evolutionary processes. We consider a stochastic model of

Abstract Primitive meteorites and interplanetary dust particles contain small grains that originated in stellar outflows and supernova explosions. These μm- and sub-μm-sized presolar grains can be
Si Isotopic Ratios in Supernovae for Presolar Grains
Primitive meteorites contain presolar grains that are considered to have traces of the nucleosynthesis at their birth as large isotopic anomalies. The isotopic signatures are important to identify
Presolar He and Ne Isotopes in Single Circumstellar SiC Grains
Noble gas isotopes in presolar silicon carbide (SiC) dust grains from primitive meteorites provide, together with major element isotopic compositions, insight into the nucleosynthetic output of

TLDR
Recent instrumental advancements in secondary ion mass spectrometry (SIMS) brought about the identification of presolar silicate grains, which are stardust that condensed in stellar outflows or stellar ejecta, and was incorporated in meteorites.
Reaction rate uncertainties and 26Al in AGB silicon carbide stardust
Context. Stardust is a class of presolar grains each of which presents an ideally uncontaminated stellar sample. Mainstream silicon carbide (SiC) stardust formed in the extended envelopes of

Can Stellar Dynamics Explain the Metallicity Distributions of Presolar Grains
The majority of presolar circumstellar SiC and Al2O3 grains found in meteorites are inferred to have originated in asymptotic giant branch (AGB) stars that were more metal-rich than the Sun despite
