Ejecta cloud from the AIDA space project kinetic impact on the secondary of a binary asteroid: II. fates and evolutionary dependencies
Yang Yu, Patrick Michel
This paper presents a quantitative study of the evolution of the ejecta cloud released from a hypervelocity impact on a binary asteroid. We performed numerical simulations of the p…
Ejecta Cloud from a Kinetic Impact on the Secondary of a Binary Asteroid: I. Mechanical Environment and Dynamic Model
Yang Yu, Patrick Michel, Stephen R. Schwartz +2
An understanding of the post-impact dynamics of ejecta clouds are crucial to the planning of a kinetic impact mission to an asteroid, and also has great implications for the histor…
Small-body deflection techniques using spacecraft: techniques in simulating the fate of ejecta
Stephen R. Schwartz, Yang Yu, Patrick Michel +1
We define a set of procedures to numerically study the fate of ejecta produced by the impact of an artificial projectile with the aim of deflecting an asteroid. Here we develop a s…
Numerical Simulations of Collisional Disruption of Rotating Gravitational Aggregates: Dependence on Material Properties
Ronald-Louis Ballouz, Derek C Richardson, Patrick Michel +2
Our knowledge of the strengths of small bodies in the Solar System is limited by our poor understanding of their internal structures, and this, in turn, clouds our understanding of…
Numerical predictions of surface effects during the 2029 close approach of asteroid 99942 Apophis
Yang Yu, Derek C. Richardson, Patrick Michel +2
Asteroid (99942) Apophis' close approach in 2029 will be one of the most significant small-body encounter events in the near future and offers a good opportunity for in situ explor…
Topological Classifications and Bifurcations of Periodic Orbits in the Potential Field of Highly Irregular-shaped Celestial Bodies
Yu Jiang, Yang Yu, Hexi Baoyin
This paper studies the distribution of characteristic multipliers, the structure of submanifolds, the phase diagram, bifurcations and chaotic motions in the potential field of rota…
