The isotopic composition of meteorites and terrestrial planets holds important clues about
the earliest history of the Solar System and the processes of planet formation. Recent work …

Chemical and physical Earth models agree little as to the radioactive power of the planet.
Each predicts a range of radioactive powers, overlap** slightly with the other at about 24 …

We present a comprehensive evolutionary model of the Sun's protoplanetary disk,
constructed to resolve the" CAI storage problem" of meteoritics. We predict the abundances …

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

Protoplanetary disks are dispersed by viscous evolution and photoevaporation in a few
million years; in the interim small, sub-micron-sized dust grains must grow and form planets …

High‐precision bulk aluminum‐magnesium isotope measurements of calcium‐aluminum‐
rich inclusions (CAI s) from CV carbonaceous chondrites in several laboratories define a …

Renazzo-type carbonaceous (CR) chondrites are distinct from most other chondrites in
having younger chondrule 26 Al-26 Mg ages, but the significance of these ages and whether …

Chondrites consist of three major components: refractory inclusions (Ca, Al‐rich inclusions
[CAI s] and amoeboid olivine aggregates), chondrules, and matrix. Here, I summarize recent …

Ca–Al-rich inclusions (CAI) are the oldest dated objects formed in the solar system and are
pivotal reference points in early solar system chronology. Knowledge of their initial 182 …

Millimeter‐scale rock particles called chondrules are the principal components of the most
common meteorites, chondrites. Hence, chondrules were arguably the most abundant …
