Dynamics of the asteroid rings (10199) Chariklo [PDF]

open access: goldВісник Астрономічної школи, 2016
In 2014 it was reported on opening two rings around asteroid (10199) Chariklo (Braga-Ribas F., et al., 2014, Nature, 508, 72–75) and it became the fifth object of the Solar system known to have ring system, after Jupiter, Saturn, Uranus and Neptune.

Dynamics of rotationally fissioned asteroids: Source of observed small asteroid systems [PDF]

open access: greenIcarus, 2011
We present a model of near-Earth asteroid (NEA) rotational fission and ensuing dynamics that describes the creation of synchronous binaries and all other observed NEA systems including: doubly synchronous binaries, high- e binaries, ternary systems, and contact binaries. Our model only presupposes the Yarkovsky-O'Keefe-Radzievskii-Paddack (YORP) effect,

Geometric mechanics and the dynamics of asteroid pairs [PDF]

open access: greenDynamical Systems, 2005
This paper studies, using the technique of Lagrangian reduction, the geometric mechanics of a pair of asteroids in orbit about each other under mutual gravitational attraction.

Inelastic Collision Influencing the Rotational Dynamics of a Non-Rigid Asteroid (of Rubble Pile Type) [PDF]

open access: goldMathematics, 2023
We have considered here a novel particular model for dynamics of a non-rigid asteroid rotation, assuming the added mass model instead of the concept of Viscoelastic Oblate Rotators to describe the physically reasonable response of a ‘rubble pile ...

Morphology of ejecta features from the impact on asteroid Dimorphos [PDF]

open access: yesNature Communications
Hypervelocity impacts play a significant role in the evolution of asteroids, causing material to be ejected and partially reaccreted. However, the dynamics and evolution of ejected material in a binary asteroid system have never been observed directly ...

Dynamics of the Hungaria asteroids [PDF]

open access: greenIcarus, 2010
To try to understand the dynamical and collisional evolution of the Hungaria asteroids we have built a large catalog of accurate synthetic proper elements. Using the distribution of the Hungaria, in the spaces of proper elements and of proper frequencies, we can study the dynamical boundaries and the internal structure of the Hungaria region, both ...

Dynamics of the binary asteroid (379) Huenna

open access: bronzeIcarus, 2022
We aim at studying the dynamical system of the asteroid (379) Huenna and its satellite, for which a discrepancy between its predicted and observed position was reported by DeMeo et al. (2011, Icarus, 212). We compile all the available images of the system acquired with large ground-based telescopes equipped with adaptive-optics fed camera.

Fully Coherent Model of Dynamics around Binary Asteroids: Application to Didymos and the DART Impact

open access: goldThe Planetary Science Journal
The dynamical environment around binary asteroids has been studied in depth, but these models typically make assumptions about the eccentricity, shapes, or rotational stability of the asteroids.

The Dynamics of NEO Binary Asteroids [PDF]

open access: bronzeProceedings of the International Astronomical Union, 2006
AbstractThe dynamics of binary Near-Earth objects (NEO) are discussed and a simple model for the study of their dynamics is introduced. Main results on the motion and stability of binary asteroids are reviewed. The effect of perturbations external to the binary system, including solar gravity, solar radiation pressure, and planetary gravity, are ...

An Earth Encounter as the Cause of Chaotic Dynamics in Binary Asteroid (35107) 1991VH

open access: goldThe Planetary Science Journal
Among binary asteroids, (35107) 1991VH stands out as unique given the likely chaotic rotation within its secondary component. The source of this excited dynamical state is unknown. In this work, we demonstrate that a past close encounter with Earth could
