Asteroid flux towards circumprimary habitable zones in binary star systems: I. Statistical Overview
, 2015 So far, multiple stellar systems harbor more than 130 extra solar planets. Dynamical simulations show that the outcome of planetary formation process can lead to various planetary architecture (i.e.

The Dynamics of the Trojan Asteroids [PDF]
Symposium - International Astronomical Union, 1994 The state of the art in the dynamics of the Trojan asteroids has progressed rapidly, since it has been possible to perform numerical integrations of many orbits for millions of years. Accurate proper elements are now computed by the synthetic method, that is from the output of a numerical integration; their stability, at least for time spans of a few ...

Radiation Forces and Trajectory of Hayabusa2♯ Target 1998 KY26
The Astrophysical Journal LettersSmall near-Earth asteroid 1998 KY _26 has recently become an object of interest because it is the target of the Hayabusa2 ♯ mission and because challenges in fitting its astrometric data have led to classifying it as a dark comet.

Secular dynamics around uniformly rotating asteroids
Monthly Notices of the Royal Astronomical Society, 2019 The dynamical behaviours of spacecrafts moving around uniformly rotating asteroids are investigated in this work. Based on the generalized inertia integrals of asteroids, the expression of the disturbing potential is derived as a trigonometric series in terms of the mean anomaly, geographical longitude of ascending node and argument of pericentre.

Effects of asteroid belt and oblateness on the stability and orbits near triangular Lagrange points
Results in PhysicsThis study investigates the dynamics of an infinitesimal body within the context of the restricted three-body problem, incorporating perturbations arising from the asteroid belt and the oblateness effects of the three bodies.

Geo-engineering using dust grains in heliotropic elliptical orbits [PDF]
, 2011 This paper examines the concept of a Saturn-like Earth ring comprised of dust grains to offset global warming. A new family of non-Keplerian periodic orbits, under the effects of solar radiation pressure and the Earth’s oblateness J2 perturbation, is ...

The dynamics about asteroid (162173) Ryugu
Celestial Mechanics and Dynamical AstronomyAbstractThe dynamical environment around the asteroid (162173) Ryugu is analyzed in detail using a constant-density polyhedron model based on the measurements from the Hayabusa2 mission. Six exterior equilibrium points (EPs) are identified along the ridge line of Ryugu, and their topological classifications fall into two distinctive categories.
