Wallner, Anton; Melber, K.; Merchel, S.; Ott, Ulrich; Forstner, O; Golser, Robin; Kutschera, Walter; Priller, Alfred; Steier, Peter

Description

Nanodiamonds are stardust grains commonly found in primitive meteorites. They survived the formation of the solar system and kept their own individuality. Measurements of trace-element isotopic signatures in these grains will help understanding heavy element nucleosynthesis in massive stars and dust formation from their ejecta. We have continued previous attempts to search for stable Pt isotope anomalies in nanodiamonds via trace element accelerator mass spectrometry (TEAMS). The installation...[Show more]
