▪ Abstract We present a review of nucleosynthesis in AGB stars outlining the development of
theoretical models and their relationship to observations. We focus on the new high …

Abstract Forty years ago Burbidge, Burbidge, Fowler, and Hoyle combined what we would
now call fragmentary evidence from nuclear physics, stellar evolution and the abundances …

Compositional models of the Earth are critically dependent on three main sources of
information: the seismic profile of the Earth and its interpretation, comparisons between …

The isotopic composition of meteorites reveals a fundamental dichotomy between non-
carbonaceous (NC) and carbonaceous (CC) meteorites. However, the origin of this …

We present results of a study of the 53Mn-53Cr systematics in various solar system objects:
angrites, eucrites, chondrites, diogenites, pallasites, the Earth and the Moon, and SNC …

We address the first several hundred million years of Earth's history. The Moon-forming
impact left Earth enveloped in a hot silicate atmosphere that cooled and condensed over∼ …

With a half-life of 0.73 Myr, the 26 Al-to-26 Mg decay system is the most widely used short-
lived chronometer for understanding the formation and earliest evolution of the solar …

The short-lived radionuclide aluminium-26 (26Al) isotope is a major heat source for early
planetary melting. The aluminium-26–magnesium-26 (26Al-26Mg) decay system also …

The timing of the formation of the first solids in the solar system remains poorly constrained.
Micrometer-scale, high-precision magnesium (Mg) isotopic analyses demonstrate that Earth …

Available evidence strongly suggests that the HED (howardite, eucrite, diogenite) meteorites
are samples of asteroid 4 Vesta. Abundances of the moderately siderophile elements (Ni …
