Scientific paper

We report the isotopic composition of molybdenum in three mainstream presolar SiC grains from Murchison. Normalized to terrestrial Mo isotopic composition and to the pure s-process isotope Mo-96, all three grains are strongly depleted in p-process Mo-92 and Mo-94, r- and s-process Mo-95, Mo-97, and Mo-98, and r-process Mo-100. The largest depletions are in the pure p- and r-process isotopes, as expected from s-process nucleosynthesis in AGB stars.
