Strontium and barium isotopes in presolar silicon …

We have studied the carbon, silicon, iron, and nickel isotopic compositions of presolar silicon carbide (SiC) grains from asymptotic giant branch (AGB) stars to better understand GCE. Since only the neutron-rich nuclides in these grains have been heavily in uenced by the parent star, the neutron-poor nuclides serve as GCE proxies.

Silicon carbide ''stardust'' in meteorites leads to …

The microscopic grains of silicon carbide — a thousand times smaller than the average width of a human hair — were part of the construction materials that built the sun and planetary system. Born in nova outbursts, which are repeated aclysmic eruptions by certain types of white dwarf stars, the silicon carbide grains are found today eedded in primitive meteorites.

Presolar silicon carbide grains and their parent stars The elemental abundances in the stellar sources of the SiC grains are inferred by using condensation calculations. These elemental abundances, together with C isotopic compositions, are used to identify possible groups of carbon stars that may have contributed SiC grains to the presolar dust cloud.

[1906.10776] Presolar Silicon Carbide Grains of Types Y …

25/6/2019· We report Mo isotopic compositions of 37 presolar SiC grains of types Y (19) and Z (18), rare types commonly argued to have formed in lower-than-solar metallicity asymptotic giant branch (AGB) stars. Direct comparison of the Y and Z grain data with data for mainstream grains from AGB stars of close-to-solar metallicity demonstrates that the three types of grains have indistinguishable Mo
