Planetesimal rings as the cause of the Solar System's planetary architecture
Astronomical observations reveal that protoplanetary disks around young stars commonly
have ring-and gap-like structures in their dust distributions. These features are associated …

Magma ocean, water, and the early atmosphere of Venus
The current state and surface conditions of the Earth and its twin planet Venus are drastically
different. Whether these differences are directly inherited from the earliest stages of …

Origin of life-forming volatile elements in the inner Solar System
Volatile elements such as hydrogen, carbon, nitrogen and oxygen are essential ingredients
to build habitable worlds like Earth, but their origin and evolution on terrestrial planets …

Degassing of early-formed planetesimals restricted water delivery to Earth
The timing of delivery and the types of body that contributed volatiles to the terrestrial planets
remain highly debated,. For example, it is unknown if differentiated bodies, such as that …

Three-dimensional Global Simulations of Type-II Planet–Disk Interaction with a Magnetized Disk Wind. I. Magnetic Flux Concentration and Gap Properties
Giant planets embedded in protoplanetary disks (PPDs) can create annulus density gaps
around their orbits in the type-II regime, potentially responsible for the ubiquity of annular …

Igneous meteorites suggest Aluminium-26 heterogeneity in the early Solar Nebula
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 …

Chondrules reveal large-scale outward transport of inner Solar System materials in the protoplanetary disk
Dynamic models of the protoplanetary disk indicate there should be large-scale material
transport in and out of the inner Solar System, but direct evidence for such transport is …
