Transport of dust across the Solar System: Constraints on the spatial origin of individual micrometeorites from cosmic-ray exposure
Reto Georg Trappitsch, Xuan Li
The origin of micrometeorites (MMs) from asteroids and comets is well-established, but the relative contribution from these two classes remains poorly resolved. Likewise, determining the precise origin of individual MMs is an open challenge. Here, cosmic-r ...
Royal Soc2024Shape Models of Lucy Targets (3548) Eurybates and (21900) Orus from Disk-integrated Photometry
We use our new light curves, along with historical data, to determine the rotation state, photometric properties, and convex shape models of the targets of the Lucy mission (3548) Eurybates and (21900) Orus. We determine a retrograde spin for both targets, ...
IOP Publishing Ltd2023Unique large diamonds in a ureilite from Almahata Sitta 2008 TC3 asteroid
The Almahata Sitta MS-170 ureilite (a piece of a breccia originating from the asteroid, 2008 TC3) consists mainly of olivine, with many diamond and graphite grains existing between the olivine grains. The occurrences of the diamonds are unique; i.e., (i) s ...
Pergamon-Elsevier Science Ltd2015A deep crust-mantle boundary in the asteroid 4 Vesta
Philippe Gillet, Harold Gabriel Eugène Justin Clenet
The asteroid 4 Vesta was recently found to have two large impact craters near its south pole, exposing subsurface material. Modelling suggested that surface material in the northern hemisphere of Vesta came from a depth of about 20 kilometres, whereas the ...
Nature Publishing Group2014The structure of the asteroid 4 Vesta as revealed by models of planet-scale collisions
Asteroid 4 Vesta seems to be a major intact protoplanet, with a surface composition similar to that of the HED (howardite-eucrite-diogenite) meteorites(1-4). The southern hemisphere is dominated by a giant impact scar(5), but previous impact models(6-8) ha ...
Nature Publishing Group2013Redox state during core formation on asteroid 4-Vesta
Core formation is the main differentiation event in the history of a planet. However, the chemical composition of planetary cores and the physicochemical conditions prevailing during core formation remain poorly understood. The asteroid 4-Vesta is the smal ...
Elsevier2013Evidence for K-rich terranes on Vesta from impact spherules
The howardite-eucrite-diogenite (HED) clan is a group of meteorites that probably originate from the asteroid Vesta. Some of them are complex breccias that contain impact glasses whose compositions mirror that of their source regions. Some K-rich impact gl ...
2009Seasonal study of directional reflectance properties of snow
We present an analysis of the hemispherical-directional reflectance factor (HDRF) of snow, using 16 seasonal datasets of the spectral range from 400 to 2,500 nm. The data was measured under clear sky conditions in Davos Dorf (Grisons, Switzerland, 1,560 m ...
2005Cristobalite inclusions in the Tatahouine achondrite: Implications for shock conditions
The mineralogy of the Tatahouine diogenite was investigated by optical microscopy, Raman micro-spectrometry, and scanning and transmission electron microscopies. Inclusions of alpha-cristobalite in orthopyroxenes, locally in symplectic association with chr ...
2002Vesta, Vestoids, and the howardite, eucrite, diogenite group: Relationships and the origin of spectral differences
Spectra of asteroid 4 Vesta and 21 small (estimated diameters less than 10 km) asteroids with Vesta-like spectral properties (Vestoids) were measured at visible and near-infrared wavelengths (similar to0.44 to similar to1.65 mum). All of the measured small ...
