This review presents our understanding of cometary dust at the end of 2017. For decades,
insight about the dust ejected by nuclei of comets had stemmed from remote observations …

Comet samples returned to Earth by the NASA Stardust mission have provided a surprising
glimpse into the nature of early Solar System materials and an epiphany on the origin of the …

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 …

Context. We investigate the formation and evolution of comet nuclei and other trans-
Neptunian objects (TNOs) in the solar nebula and primordial disk prior to the giant planet …

We report results from global ideal MHD simulations that study thin accretion disks (with
thermal scale height H/R= 0.1 and 0.05) threaded by net vertical magnetic fields. Our …

Isotopic ratios in comets provide keys for the understanding of the origin of cometary
material, and the physical and chemical conditions in the early Solar Nebula. We review …

Meteorites, which are remnants of solar system formation, provide a direct glimpse into the
dynamics and evolution of a young stellar object (YSO), namely our Sun. Much of our …

Chondrite groups (CV, CK, CR) with large average chondrule sizes have low proportions of
RP plus C chondrules, high proportions of envelo** compound chondrules, high …

The relative abundances and chemical compositions of the macroscopic components or
“inclusions”(chondrules and refractory inclusions) and fine-grained mineral matrix in …

Many igneous rocks contain mineral assemblages that are not appropriate for application of
common mineral equilibria or oxybarometers to estimate oxygen fugacity. Spinel-structured …
