Early Thermal Evolution of Planetesimals and its Impact on Processing and Dating of Meteoritic Material

, 2013
Radioisotopic ages for meteorites and their components provide constraints on the evolution of small bodies: timescales of accretion, thermal and aqueous metamorphism, differentiation, cooling and impact metamorphism.

Radioactive nuclei from cosmochronology to habitability [PDF]

, 2018
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 100 million years (short-lived radionuclides, SLRs) were present in the ...

Geo-neutrinos: a new probe of Earth's interior

, 2005
In preparation to the experimental results which will be available in the future, we study geo-neutrino production for different models of mantle convection and composition.

Fission products of superheavy elements. An investigation of the naturally occurring fission products of elements heavier than uranium [PDF]

Fission mass yields in different structural elements and mineral separates were studied for the element X. The fission component for Pu-244, and the element X are discussed along with radiogenic Xe-129 and neutron ...

Cosmic-ray exposure ages of enstatite chondrites [PDF]

, 2000
Eleven enstatite (E-) chondrites were analyzed for abundances and isotopic ratios of noble gases by total melting. Light noble gases, He, Ne and Ar are discussed. We obtained cosmic-ray exposure ages (T^) based on cosmogenic ^Ne that are divided into two

Tracer Applications of Noble Gas Radionuclides in the Geosciences

, 2013
The noble gas radionuclides, including 81Kr (half-life = 229,000 yr), 85Kr (11 yr), and 39Ar (269 yr), possess nearly ideal chemical and physical properties for studies of earth and environmental processes.

Late metal-silicate separation on the IAB parent asteroid: Constraints from combined W and Pt isotopes and thermal modelling

, 2018
The short-lived $^{182}$Hf-$^{182}$W decay system is a powerful chronometer for constraining the timing of metal-silicate separation and core formation in planetesimals and planets. Neutron capture effects on W isotopes, however, significantly hamper the
