Convergence of a Periodic Orbit Family Close to Asteroids During a Continuation
Haokun Kang, Yu Jiang, Hengnian Li
In this work, we study the continuation of a periodic orbit on a relatively large scale and discover the existence of convergence under certain conditions, which has profound signi…
Stable Periodic Orbits for Spacecrafts around Minor Celestial Bodies
Yu Jiang, Juergen Schmidt, Hengnian Li +2
We are interested in stable periodic orbits for spacecrafts in the gravitational field of minor celestial bodies. The stable periodic orbits around minor celestial bodies are usefu…
Orbital Stability Close to Asteroid 624 Hektor using the Polyhedral Model
Yu Jiang, Hexi Baoyin, Hengnian Li
We investigate the orbital stability close to the unique L4-point Jupiter binary Trojan asteroid 624 Hektor. The gravitational potential of 624 Hektor is calculated using the polyh…
Periodic Motion near the Surface of Asteroids
Yu Jiang, Hexi Baoyin, Hengnian Li
We are interested in the periodic motion and bifurcations near the surface of an asteroid. The gravity field of an irregular asteroid and the equation of motion of a particle near…
Collision and Annihilation of Relative Equilibrium Points Around Asteroids with a Changing Parameter
Yu Jiang, Hexi Baoyin, Hengnian Li
In this work, we investigate the bifurcations of relative equilibria in the gravitational potential of asteroids. A theorem concerning a conserved quantity, which is about the eige…
Orbits and Manifolds near the Equilibrium Points around a Rotating Asteroid
Yu Jiang, Hexi Baoyin, Junfeng Li +1
We study the orbits and manifolds near the equilibrium points of a rotating asteroid. The linearised equations of motion relative to the equilibrium points in the gravitational fie…
Stability and Motion around Equilibrium Points in the Rotating Plane-Symmetric Potential Field
Yu Jiang, Hexi Baoyin, Xianyu Wang +1
This study presents a study of equilibrium points, periodic orbits, stabilities, and manifolds in a rotating plane symmetric potential field. It has been found that the dynamical b…
Hamiltonian Formulation and Perturbations for Dust Motion around Cometary Nuclei
Yu Jiang, Juergen Schmidt, Hexi Baoyin +2
In this paper we analyze the dynamical behavior of large dust grains in the vicinity of a cometary nucleus. To this end we consider the gravitational field of the irregularly shape…
Order and Chaos near Equilibrium Points in the Potential of Rotating Highly Irregular-shaped Celestial Bodies
Yu Jiang, Hexi Baoyin, Xianyu Wang +4
The order and chaos of the motion near equilibrium points in the potential of a rotating highly irregular-shaped celestial body are investigated from point of view of the dynamical…
