Ferromagmatic Intrusions on Asteroid (16) Psyche May Be Magnetized
Journal of Geophysical Research: Planets, Volume 130, Issue 8, August 2025.Abstract NASA's Psyche mission will arrive at the metal‐rich asteroid (16) Psyche in 2029. The mission will test whether (16) Psyche is a remnant of a melted, differentiated planetesimal that formed a molten iron metallic core. Previous studies have suggested that a molten metallic core fluid could erupt volcanically, explaining the high metal content ...

, 2007 The water content and habitability of terrestrial planets are determined during their final assembly, from perhaps a hundred 1000-km "planetary embryos" and a swarm of billions of 1-10 km "planetesimals." During this process, we assume that water-rich ...

Planet formation in slightly inclined binary systems
EPJ Web of Conferences, 2011 One of the major problems of planet formation in close binary systems, such as α Centauri AB, is the formation of planetary embryos or cores by mutual accretion of km-sized planetesimals.

Initial mass function of planetesimals formed by the streaming instability
, 2016 The streaming instability is a mechanism to concentrate solid particles into overdense filaments that undergo gravitational collapse and form planetesimals.

Estimating the mass of the debris disc in HD 69830
, 2011 We present a method to estimate the mass of the debris disc in the HD 69830 system, which also hosts three exoplanets with Neptune-like minimum masses. By considering the range of published stellar ages, we interpret the infrared emission from the debris

Tidal Disruption of Planetesimals from an Eccentric Debris Disk Following a White Dwarf Natal Kick
The Astrophysical Journal LettersThe surfaces of many white dwarfs are polluted by metals, implying a recent accretion event. The tidal disruption of planetesimals is a viable source of white dwarf pollution and offers a unique window into the composition of exoplanet systems.

Silica-rich volcanism in the early solar system dated at 4.565 Ga
Nature Communications, 2018 Achondritic meteorites can record volcanism and crust formation on planetesimals in the early Solar System. Here, the authors date the Northwest Africa 11119 meteorite with an Al-Mg age of 4564.8 ± 0.3 Ma indicating that this is the earliest evidence of ...
