Dynamical lifetimes of asteroids in retrograde orbits [PDF]
Monthly 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.

A survey on Hungaria asteroids involved in mean motion resonances with Mars [PDF]
A&A 657, A135 (2022), 2021 Context. A region at the inner edge of the main asteroid belt is populated by the Hungaria asteroids. Among these objects, the Hungaria family is formed as the result of a catastrophic disruption of (434) Hungaria asteroid hundred million years ago. Due to the Yarkovsky effect, the fragments depending on their direction of rotation are slowly drifting ...

On the dynamics of Trojan asteroids [PDF]
Symposium - International Astronomical Union, 1996 The author's theory of Trojan asteroids (Érdi, 1988) is developed further. The motion of the Trojans is considered in the framework of the three-dimensional elliptic restricted three-body problem of the Sun-Jupiter-asteroid system including also the secular changes of Jupiter's orbital eccentricity and the apsidal motion of Jupiter's elliptic orbit. An

Dynamical evolution of basaltic asteroids outside the Vesta family in the inner main belt [PDF]
A&A 672, A97 (2023), 2023 Basaltic V-type asteroids are leftovers from the formation and evolution of differentiated planetesimals. They are thought to originate from mantles and crusts of multiple different parent bodies. Identifying the links between individual V-type asteroids and multiple planetesimals is challenging, especially in the inner part of the main asteroid belt ...

Imbalanced classification applied to asteroid resonant dynamics
Frontiers in Astronomy and Space Sciences, 2023 Introduction: Machine learning (ML) applications for studying asteroid resonant dynamics are a relatively new field of study. Results from several different approaches are currently available for asteroids interacting with the z2, z1, M1:2, and ν6 ...

On the dynamics OF NON-RIGID asteroid rotation [PDF]
Acta Astronautica, 2019 We have presented in this communication a new solving procedure for the dynamics of non-rigid asteroid rotation, considering the final spin state of rotation for a small celestial body (asteroid). The last condition means the ultimate absence of the applied external torques (including short-term effect from torques during collisions, long-term YORP ...

On The Critical Phenomena in The Dynamics of Asteroids [PDF]
International Astronomical Union Colloquium, 1999 AbstractTwo statistical effects in the long-term chaotic asteroidal dynamics are considered, namely the power-law character of the dependence of recurrence times on local Lyapunov times and the power-law decay in the tails of the recurrence distributions. The dependences in both cases are shaped by effects of anomalous transport, due to the presence of

(523599) 2003 RM: The Asteroid that Wanted to be a Comet
The Planetary Science Journal, 2023 We report a statistically significant detection of nongravitational acceleration on the subkilometer near-Earth asteroid (523599) 2003 RM. Due to its orbit, 2003 RM experiences favorable observing apparitions every 5 yr.
