Radioactive nuclei from cosmochronology to habitability
M. Lugaro, U. Ott, Á. Kereszturi
In addition to long-lived radioactive nuclei like U and Th isotopes, which have been used to measure the age of the Galaxy, also radioactive nuclei with half-lives between 0.1 and…
Origin of the p-process radionuclides 92Nb and 146Sm in the early Solar System and inferences on the birth of the Sun
Maria Lugaro, Marco Pignatari, Ulrich Ott +4
The abundances of 92Nb and 146Sm in the early Solar System are determined from meteoritic analysis and their stellar production is attributed to the p process. We investigate if th…
Stellar origin of the 182Hf cosmochronometer and the presolar history of solar system matter
Maria Lugaro, Alexander Heger, Dean Osrin +7
Among the short-lived radioactive nuclei inferred to be present in the early solar system via meteoritic analyses, there are several heavier than iron whose stellar origin has been…
New attempts to understand nanodiamond stardust
Ulrich Ott, Astrid Besmehn, Khalil Farouqi +5
We report on a concerted effort aimed at understanding the origin and history of the pre-solar nanodiamonds in meteorites including the astrophysical sources of the observed isotop…
