The detection and characterization of large populations of pebbles in protoplanetary disks
have motivated the study of pebble accretion as a driver of planetary growth. This review …

Defining the age of the Moon has proven to be an elusive task because it requires reliably
dating lunar samples using radiometric isotopic systems that record fractionation of parent …

Previous analyses of mid-infrared water spectra from young protoplanetary disks observed
with the Spitzer-IRS found an anticorrelation between water luminosity and the millimeter …

Super-Earths–planets with sizes between the Earth and Neptune–are found in tighter orbits
than that of the Earth around more than one third of main sequence stars. It has been …

Geochemical and astronomical evidence demonstrates that planet formation occurred in two
spatially and temporally separated reservoirs. The origin of this dichotomy is unknown. We …

The giant impact hypothesis remains the leading theory for lunar origin. However, current
models struggle to explain the Moon's composition and isotopic similarity with Earth. Here …

There is a long-standing debate regarding the origin of the terrestrial planets' water as well
as the hydrated C-type asteroids. Here we show that the inner Solar System's water is a …

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 …

Comparing compositional models of the terrestrial planets provides insights into
physicochemical processes that produced planet-scale similarities and differences. The …

At least 30% of main sequence stars host planets with sizes of between 1 and 4 Earth radii
and orbital periods of less than 100 days. We use N-body simulations including a model for …
