Numerical Determination of the Gravitational Cross Sections of an Accreting Binary
The Astrophysical JournalA significant amount of work has been devoted to the study of small binary solar system objects. The majority of these binaries, especially among the near-Earth or main belt asteroids, have small radius ratios, implying a large difference in size between

Near-Infrared Spectroscopy of Centaurs and Irregular Satellites [PDF]
, 2000 We have obtained near-infrared spectra of the four brightest known Centaurs and of five irregular satellites of giant planets. Many of these objects show 1.5 and 2.0 μm absorption bands indicative of water ice, including 1997 CU_(26), Pholus, Phoebe (S9),

THE PUZZLING MUTUAL ORBIT OF THE BINARY TROJAN ASTEROID (624) HEKTOR
, 2014 International audienceAsteroids with satellites are natural laboratories to constrain the formation and evolution of our solar system. The binary Trojan asteroid (624) Hektor is the only known Trojan asteroid to possess a small satellite. Based on W.

Asteroid Satellite Inspired Optimization
Asteroid satellite systems, as important binary or multi-body structures in the solar system, are of great significance to the study of astrophysics and orbital mechanics. This paper proposes a heuristic optimization algorithm based on the asteroid satellite discovery process—the Asteroid Satellite Inspired Optimization (ASIO) algorithm. This algorithm

Asteroid-Satellite Perturbation Optimization
Asteroid-Satellite Perturbation Optimization (ASP-O) is a complex nonlinear dynamical problem, characterized by gravitational interactions between the primary asteroid and its satellite, as well as orbital variations caused by external perturbations.
