The Nekhoroshev Theorem and the Asteroid Belt Dynamical System

Celestial Mechanics and Dynamical Astronomy, 1997
This paper presents some applications of the so-called Nekhoroshev's theorem [\textit{N. N. Nekhoroshev}, Russ. Math. Surveys 32, No. 6, 1-65 (1977; Zbl 0389.70028)] to Hamiltonian problems of celestial mechanics, and particularly to the qualitative dynamical structure of the asteroid belt.

Dynamic and Physical Considerations on the Asteroids Density

Earth, Moon, and Planets, 2000
High quality new data on the asteroid mass and volume were produced in the last years from both extra-atmospheric instruments and the groundbased high-performance telescopes. This paper presents a synthesis of these resultsin terms of the asteroid density, taking into account several techniques, and the possible correlation of the density through the ...

Dynamics of Distant Moons of Asteroids

Icarus, 1997
Abstract We introduce a new analytic method for treating the orbital motions of objects about asteroids and planets. For an asteroid following a circular path around the Sun, we rewrite Jacobi's integral of the motion in terms of the orbital elements relative to the asteroid.

Dynamical study of the Hilda asteroids

Astrophysics and Space Science, 1976
Schubart's (1968) model of a planar elliptic restricted three-body problem is used to study the orbital motion of the Hilda asteroids from the Palomar-Leiden Survey. The 3:2 resonant coupling to Jupiter of some of these small asteroids is found to be stable.

Asteroid dynamics with GAIA

2015
The astrometric mission Gaia of the European Space Agency (ESA) was launched in December 2013 and started the scientific phase of its 5-years-long, whole-sky survey in July 2014.

An Introduction to the Dynamics of Trojan Asteroids

2009
The dynamics of Trojan asteroids constitutes one of the richest fields of celestial mechanics, as a real application of the three-body problem. It involves the L 4 and L 5 Lagrange points and the conditions of stability around these two points. In this chapter we propose to present the fundamentals of the dynamics of Trojan asteroids.

The Physics of Asteroids and Their Junction with Dynamics

2009
The study of asteroid families is an important current topic. New insights obtained by dynamical considerations motivating the interest in completing the knowledge of the physics and the composition inside asteroid families. The discovery of young families offers a new frame of study of interaction between the family members, the family and the other ...

Dynamics of Planet-Crossing Asteroids

1999
A small, but by no means negligible, fraction of the small bodies of the Solar System is on planet-crossing orbits, including Earth-crossing ones. The dynamics of planet-crossing asteroids/comets is strongly controlled by the occurrence of close approaches.

Statistical Challenges in Asteroid Dynamics

1997
Observational data on asteroids, orbits especially, have to be interpreted in terms of origin and evolutionary processes. Cluster of asteroids are part of the puzzle. They are groupings of asteroids in the phase space of proper orbital elements. The lasts are quasi-integrals of motion, stable over very long intervals of time.
