Challenge in Arrokoth’s Single Merger to Achieve the Shape’s Principal Axis Configuration
The Planetary Science JournalThe cold-classical Kuiper Belt Object 486958 Arrokoth is a contact binary composed of two flattened lobes, Weeyo and Wenu, closely aligned along their principal axes, despite each lobe having a highly irregular shape.

Asteroid Satellite Discovery Optimization
The discovery of asteroid-satellite systems not only reveals the formation and evolution mechanisms of small solar system bodies but also provides insights into the optimization of complex systems. This paper proposes a heuristic optimization algorithm based on the principles of asteroid-satellite discovery.

Pluto-Charon: a test of the astrometric approach for finding asteroid satellites
, 2003 International audienceThe astrometric method to find asteroid satellites is based on the search for the reflex effect on the primary object due to the orbital motion of a possible satellite (Monet & Monet 1998, Kikwaya et al. 2002).

Physical and Mutual Orbit Characteristics of Near-Earth Binary Asteroid (163693) Atira
The Planetary Science JournalWe report physical and mutual orbit characteristics of near-Earth binary asteroid (163693) Atira. Using S -band (2380 MHz, 12.6 cm) radar observations from the Arecibo Observatory and several epochs of lightcurve observations from 2003 to 2019 with SHAPE

Geo-engineering using dust grains in heliotropic elliptical orbits
, 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 ...
