Volatile depletion in rocky planets as a chemical fingerprint of hybrid accretion

Haiyang S. Wang, Anders Johansen, Ziyan Xu +7

Volatile depletion in rocky planets relative to their host stars is commonplace in both the Solar System and exoplanetary systems, yet the connections between planet formation and…

Direct detection of hydrogen reveals a new macroscopic crustal water reservoir on early Mars

Estrid Buhl Naver, Katrine Wulff Nikolajsen, Martin Sæbye Carøe +13

The next great leap in Martian exploration will be the return of samples to Earth. To ensure the maximum scientific return from studying these samples, the development and utilisat…

Interstellar Ices as Carriers of Supernova Material to the Early Solar System

Martin Bizzarro, Martin Schiller, Jesper Holst +10

Planetary materials show systematic variations in their nucleosynthetic isotope compositions that resonate with orbital distance. The origin of this pattern remains debated, limiti…

The cosmochemistry of planetary systems

Martin Bizzarro, Anders Johansen, Caroline Dorn

Planets form and obtain their compositions from the leftover material present in protoplanetary disks of dust and gas surrounding young stars. The chemical make-up of a disk influe…

The Ni isotopic composition of Ryugu reveals a common accretion region for carbonaceous chondrites

Fridolin Spitzer, Thorsten Kleine, Christoph Burkhardt +88

The isotopic compositions of samples returned from Cb-type asteroid Ryugu and Ivuna-type (CI) chondrites are distinct from other carbonaceous chondrites, which has led to the sugge…

Anatomy of rocky planets formed by rapid pebble accretion III. Partitioning of volatiles between planetary core, mantle, and atmosphere

Anders Johansen, Thomas Ronnet, Martin Schiller +2

Volatile molecules containing hydrogen, carbon, and nitrogen are key components of planetary atmospheres. In the pebble accretion model for rocky planet formation, these volatile s…
