Asteroid families: properties, recent advances, and future opportunities

B Novaković, D Vokrouhlický, F Spoto… - Celestial Mechanics and …, 2022 - Springer
Collisions are one of the key processes shaping planetary systems. Asteroid families are
outcomes of such collision still identifiable across our solar system. The families provide a …

Asteroid pairs: a complex picture

P Pravec, P Fatka, D Vokrouhlický, P Scheirich… - Icarus, 2019 - Elsevier
We studied a sample of 93 asteroid pairs, ie, pairs of genetically related asteroids that are on
highly similar heliocentric orbits. We estimated times elapsed since separation of pair …

Main belt asteroid collision histories: Cratering, ejecta, erosion, catastrophic dispersions, spins, binaries, tops, and wobblers

KA Holsapple - Planetary and Space Science, 2022 - Elsevier
This is a study of the collisional history of the asteroids in the main asteroid belt. Over the∼
4.5 Byr of the belt existence, every asteroid collided with others a multitude of times …

Machine-learning identification of asteroid groups

V Carruba, S Aljbaae, A Lucchini - Monthly Notices of the Royal …, 2019 - academic.oup.com
Asteroid families are groups of asteroids that share a common origin. They can be the
outcome of a collision or be the result of the rotational failure of a parent body or its satellites …

ABSTRACT We apply the Hierarchical Clustering method (HCM) and Selective Backward
Integration method (BIM) to search for associated families and young families for all main …

Recent formation and likely cometary activity of near-Earth asteroid pair 2019 PR2–2019 QR6

P Fatka, NA Moskovitz, P Pravec… - Monthly Notices of …, 2022 - academic.oup.com
Asteroid pairs are genetically related asteroids that recently separated (< few million years),
but still reside on similar heliocentric orbits. A few hundred of these systems have been …

Direct N-body Simulations of Satellite Formation around Small Asteroids: Insights from DART's Encounter with the Didymos System

HF Agrusa, Y Zhang, DC Richardson… - The Planetary …, 2024 - iopscience.iop.org
We explore binary asteroid formation by spin-up and rotational disruption considering the
NASA DART mission's encounter with the Didymos–Dimorphos binary, which was the first …

Spinup and Disruption of Interstellar Asteroids by Mechanical Torques, and Implications for 1I/2017 U1 ('Oumuamua)

T Hoang, A Loeb, A Lazarian, J Cho - The Astrophysical Journal, 2018 - iopscience.iop.org
The discovery of the first interstellar asteroid, 1I/2017 U1 ('Oumuamua), has opened a new
era for research on interstellar objects. In this paper, we study the rotational dynamics of …

A search for young asteroid pairs with close orbits

ED Kuznetsov, AE Rosaev, E Plavalova… - Solar System …, 2020 - Springer
We analyzed the dynamic evolution of a number of young asteroid pairs in close orbits in
order to constrain their ages. Several methods of pair selection and estimation of their age …
