Surface Modifications of a Space-weathered Ryugu Sample and the Reflectance Spectral Response
The Planetary Science JournalReflectance spectra from the surface of asteroid Ryugu, measured by the Hayabusa2 spacecraft, exhibit a metal-OH absorption at ∼2.7 μ m that is approximately half as deep as the returned samples measured in the laboratory and shifted toward longer ...

Size-dependent modification of asteroid family Yarkovsky V-shapes [PDF]
, 2017 Context. The thermal properties of the surfaces of asteroids determine the magnitude of the drift rate cause by the Yarkovsky force. In the general case of Main Belt asteroids, the Yarkovsky force is indirectly proportional to the thermal inertia, Γ. Aim.

Keck and Gemini Characterization of Hayabusa2# Rendezvous Target 1998 KY26
The Astronomical JournalNear-Earth object (NEO) 1998 KY _26 is a target of the Hayabusa2# spacecraft, which it will rendezvous with in 2031 July. The asteroid has been noted to rotate rapidly and has a large out-of-plane nongravitational acceleration.

Evidence of Possible Spectral Variability in the Patroclus–Menoetius Binary System
The Planetary Science JournalWe present new visible-wavelength spectroscopic observations of the Patroclus–Menoetius binary system in the Jupiter Trojan population. Motivated by previously published spectra from different instruments that showed evidence of significant longitudinal ...

Meteoritics &Planetary Science, EarlyView.Abstract We report new results from a study of shock‐related features in the L6 ordinary chondrites Northwest Africa (NWA) 4672 and NWA 12841. Our observations confirm the occurrence of eight high‐pressure (HP) minerals in each meteorite, namely, ringwoodite, majorite, akimotoite, wadsleyite, albitic jadeite, lingunite, tuite, and xieite.

Dynamical environment in the vicinity of asteroids with an application to 41 Daphne
Results in Physics, 2018 We studied the dynamical environment in the vicinity of the primary of the binary asteroid. The gravitational field of the primary is calculated by the polyhedron model with observational data of the irregular shape. The equilibrium points, zero-velocity

Mineralogy and Surface Composition of Asteroids [PDF]
, 2015 Methods to constrain the surface mineralogy of asteroids have seen considerable development during the last decade with advancement in laboratory spectral calibrations and validation of our interpretive methodologies by spacecraft rendezvous missions. This has enabled the accurate identification of several meteorite parent bodies in the main asteroid ...
