A Long‐Lived Planetesimal Dynamo Powered by Core Crystallization
Geophysical Research Letters, 2021 The existence of numerous iron meteorite groups indicates that some planetesimals underwent melting that led to metal‐silicate segregation, sometimes producing metallic cores.

Effect of the Planetesimal Belt on the Dynamics of the Restricted Problem of 2 + 2 Bodies
Applied Sciences (Switzerland), 2022 In this paper, we study the existence and stability of collinear and noncollinear equilibrium points within the frame of the perturbed restricted problem of 2 + 2 bodies by a planetesimal belt.

Planetesimal formation starts at the snow line [PDF]
Astronomy and Astrophysics, 2017 Planetesimal formation stage represents a major gap in our understanding of the planet formation process. The late-stage planet accretion models typically make arbitrary assumptions about planetesimals and pebbles distribution while the dust evolution ...

Low strength and a shared size distribution connect the hot and cold Kuiper belt populations [PDF]
Nature CommunicationsUnderstanding how the observed size distribution of Kuiper Belt objects emerged from the primordial planetesimal population remains a major challenge in planetary science.

Recurrent planetesimal formation in an outer part of the early solar system [PDF]
Scientific ReportsThe formation of planets in our solar system encompassed various stages of accretion of planetesimals that formed in the protoplanetary disk within the first few million years at different distances to the sun.

Size Ranges of Magnetic Domain States in Tetrataenite
Geochemistry, Geophysics, Geosystems, 2022 Paleomagnetic studies of meteorites provide unique constraints on the evolution of magnetic fields in the early solar system. These studies rely on the identification of magnetic minerals that can retain stable magnetizations over ≳4.5 billion years (Ga).

The Astrophysical Journal, 2023 We model the early stages of planet formation in the solar system, including continual planetesimal formation, and planetesimal and pebble accretion onto planetary embryos in an evolving disk driven by a disk wind.

Planetesimal Initial Mass Functions Following Diffusion-regulated Gravitational Collapse
The Astrophysical Journal, 2023 The initial mass function (IMF) of planetesimals is of key importance for understanding the initial stages of planet formation, yet theoretical predictions so far have been insufficient in explaining the variety of IMFs found in simulations.

Ice Sublimation in Planetesimals Formed at the Outward Migrating Snowline
The Astrophysical Journal Letters, 2023 Isotopic studies of meteorites suggest that planetesimals were formed as two distinct populations: noncarbonaceous (NC) and carbonaceous (CC) reservoirs.
