A Comparative Study of Infrared Asteroid Surveys: IRAS, AKARI, and WISE
, 2014 We present a comparative study of three infrared asteroid surveys based on the size and albedo data from the Infrared Astronomical Satellite (IRAS), the Japanese infrared satellite AKARI, and the Wide-field Infrared Survey Explorer (WISE).

Formation and Evolution of Binary Asteroids
, 2015 Satellites of asteroids have been discovered in nearly every known small body population, and a remarkable aspect of the known satellites is the diversity of their properties.

The role of chaotic resonances in the solar system [PDF]
, 2001 Our understanding of the Solar System has been revolutionized over the past decade by the finding that the orbits of the planets are inherently chaotic. In extreme cases, chaotic motions can change the relative positions of the planets around stars, and ...

Asteroid Companions in the Visible: WFPC 2 Images
The Planetary Science JournalWe report the observation of six asteroidal companions in direct images of five asteroids from Hubble Space Telescope (HST). These are (45) Eugenia, (87) Sylvia, (93) Minerva, (107) Camilla (the discovery observation for this companion), and (121 ...

The analemma criterion: accidental quasi-satellites are indeed true quasi-satellites
, 2016 In the Solar system, a quasi-satellite is an object that follows a heliocentric path with an orbital period that matches almost exactly with that of a host body (planetary or not).

Chaotic rotation and evolution of asteroids and small planets in high-eccentricity orbits around white dwarfs [PDF]
, 2019 Observed planetary debris in white dwarf atmospheres predominately originate from the destruction of small bodies on highly eccentric (>0.99) orbits. Despite their importance, these minor planets have coupled physical and orbital evolution, which has ...

Advanced Materials, EarlyView.All‐perovskite tandem solar cells are evaluated under low‐intensity and low‐temperature (LILT) conditions relevant to space environments. Distinct loss regimes emerge, where weaker entropic mixing causes halide segragation below ≈240 K going along with a strong current imbalance, while poor electron transport in C60 dominates.

Influence of Planetary Flyby Events on Binary Asteroid’s Impact Risk
The Astronomical JournalBinary asteroids (BAs) may collide, stay in orbit, or dissociate after a close planetary flyby. The outcome is uncertain due to uncertainties in both the BA’s heliocentric orbit and mutual orbit.

The Perturbed Full Two-body Problem: Application to Post-DART Didymos
The Planetary Science Journal, 2023 With the successful impact of the NASA Double Asteroid Redirection Test (DART) spacecraft in the Didymos–Dimorphos binary asteroid system, we provide an initial analysis of the post-impact perturbed binary asteroid dynamics.
