Dynamics of the Hungaria asteroids [PDF]

open access: yesIcarus, 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 ...

Survey of secular resonances in the asteroid belt [PDF]

open access: yesSerbian Astronomical Journal, 2022
Using a recently introduced synthetic method to compute the asteroid secular frequencies (Knežević and Milani 2019), in this paper we survey the locations of secular resonances in the 9 dynamically distinct zones of the asteroid belt.

Dynamics of asteroid systems post-rotational fission

open access: yesAstronomy & Astrophysics, 2022
Asteroid binaries found among the near-Earth objects are believed to have formed from rotational fission. In this paper, we study the dynamical evolution of asteroid systems the moment after fission. The model considers two bodies the moment after a contact binary separates due to rotational fission.

The relationship between the `limiting' Yarkovsky drift speed and asteroid families' Yarkovsky V-shape [PDF]

open access: yesSerbian Astronomical Journal, 2020
The Yarkovsky effect is an important force to consider in order to understand the long-term dynamics of asteroids. This non-gravitational force affects the orbital elements of objects revolving around a source of heat, especially their semi ...

Dynamical evolution of cometary asteroids [PDF]

open access: yesMonthly Notices of the Royal Astronomical Society, 1998
ABSTRA C T We present results from long-term numerical integrations of hypothetical Jupiter-family comets (JFCs) over time-scales in excess of the estimated cometary active lifetime. During inactive periods these bodies could be considered as ‘cometary’ near-Earth objects (NEOs) or ‘cometary asteroids’. The contribution of cometary asteroids to the NEO

Dynamical lifetimes of asteroids in retrograde orbits [PDF]

open access: yesMonthly Notices of the Royal Astronomical Society, 2017
The population of known minor bodies in retrograde orbits ($i > 90 ^{\circ}$) that are classified as asteroids is still growing. The aim of our study was to estimate the dynamical lifetimes of these bodies by use of the latest observational data, including astrometry and physical properties.

Dynamical Masses of 20 Asteroids Determined with Gaia DR3 Asteroid Observations

open access: yesThe Astronomical Journal, 2023
Abstract We combined the ground-based and Gaia Data Release 3 (DR3) asteroid observations to determine the masses of 20 asteroids with asteroid–asteroid close encounters. In order to take full advantage of the high-precision observations from Gaia, we use the Fisher information to select appropriate model parameters and the modified ...

DYNAMICAL EFFECTS FROM ASTEROID BELTS FOR PLANETARY SYSTEMS [PDF]

open access: yesInternational Journal of Bifurcation and Chaos, 2004
The orbital evolution and stability of planetary systems with interaction from the belts is studied using the standard phase-plane analysis. In addition to the fixed point which corresponds to the Keplerian orbit, there are other fixed points around the inner and outer edges of the belt.
