Collisions of Planetesimals and Formation of Planets [PDF]
Proceedings of the International Astronomical Union, 2015 AbstractWe present preliminary results of models of terrestrial planet formation using on the one hand classical numerical integration of hundreds of small bodies on CPUs and on the other hand—for comparison—the results of our GPU code with thousands of small bodies which then merge to larger ones.

Measurements of Dielectric Properties of Chang’E‐5 Lunar Samples
Journal of Geophysical Research: Planets, Volume 131, Issue 3, March 2026.Abstract The Chang’E‐5 samples are the youngest lunar materials collected to date. Determining their dielectric properties is essential for understanding the physical characteristics of lunar regolith and refining its dielectric model. In this study, the real part of permittivity and the loss tangent of the Chang’E‐5 samples were systematically ...

How planetesimal accretion affects the composition of gas giants [PDF]
, 2022 openPlanet formation is still a debated process in the scientific community. The state of art theories predict planets to form inside protoplanetary disks made of gas and dust orbiting around newly formed stars.

Post-main sequence thermal evolution of planetesimals
, 2023 White dwarfs that have accreted planetary materials provide a powerful tool to probe the interiors and formation of exoplanets. In particular, the high Fe/Si ratio of some white dwarf pollutants suggests that they are fragments of bodies that were heated

From planetesimals to planets with N-body simulations in the giant-planet formation region
Astronomy & AstrophysicsThe cores of wide-orbit giant planets can form via pebble accretion if large planetesimals form in the outer regions of protoplanetary discs at sufficiently early times.

Geochemical and petrographic re‐evaluation of ungrouped iron meteorites from Western Australia
Meteoritics &Planetary Science, Volume 61, Issue 3, Page 444-465, March 2026.Abstract Under the current classification scheme, ungrouped irons make up ~11% of all recognized iron meteorites. A further ~7% of iron meteorites are currently classified as simply “irons” and are yet to be fully classified. To potentially classify these meteorites, newer approaches, including either statistical modeling or advanced geochemical ...

Pebbles versus planetesimals: the case of Trappist-1
, 2019 We present a study into the formation of planetary systems around low mass stars similar to Trappist-1, through the accretion of either planetesimals or pebbles. The aim is to determine if the currently observed systems around low mass stars could favour
