VIS‐to‐MIR reflectance and Raman spectroscopy of the CM2 NWA 12184 carbonaceous chondrite
Meteoritics &Planetary Science, Volume 60, Issue 3, Page 570-595, March 2025.Abstract The spectral analysis of CM meteorites can help to constrain the mineralogical composition of their parent body, the C‐type asteroids. The CM2 NWA 12184 was spectrally examined employing seven complementary techniques at different spatial resolutions, including VIS‐to‐MIR reflectance and Raman spectroscopy.

, 2017 Asteroids that are targets of spacecraft missions are interesting because they present us with an opportunity to validate ground-based spectral observations. One such object is near-Earth asteroid (NEA) (162173) Ryugu, which is the target of the Japanese

Meteoritics &Planetary Science, Volume 60, Issue 3, Page 616-631, March 2025.Abstract Results of microanalysis study of NWA 869 meteorite, an ordinary chondrite, where silicates, Fe‐Ni alloys, and troilite are major constituents, are reported. The presented study of microtextures in metallic and sulfide grains provides information on processes occurring from the asteroid's accretion, through the impacts until cooling.

The Biological Bulletin, 1975 1. Intraspecific agonistic behavior, called bouts, which involves ray interactions between individual sea stars, is reported in species from all three living orders of asteroids and described for Patiria miniata and Pycnopodia helianthoides. This behavior indicates a certain sensitivity to conspecific contact on the aboral surface, in which each ...

Meteoritics &Planetary Science, EarlyView.Abstract Multiple generations of calcite and dolomite precipitated in CM chondrites during ice melting events that led to episodes of liquid water. Models and laboratory analysis have suggested a long‐term transition from oxidizing to reducing conditions during aqueous alteration on the CM parent body.

Northwest Africa 13489: A Strongly Metamorphosed Ungrouped Carbonaceous Chondrite
Meteoritics &Planetary Science, EarlyView.Abstract NWA 13489 is a meteorite that has been classified as a brachinite. Brachinites are olivine‐rich primitive achondrites representing residual products after a variable degree of silicate melt extraction on a barely differentiated, noncarbonaceous asteroid.

Earth's Minimoons: Opportunities for Science and Technology
Frontiers in Astronomy and Space Sciences, 2018 Twelve years ago the Catalina Sky Survey discovered Earth's first known natural geocentric object other than the Moon, a few-meter diameter asteroid designated 2006 RH120. Despite significant improvements in ground-based telescope and detector technology

Meteoritics &Planetary Science, EarlyView.Abstract Carbonaceous chondrites are meteorites originating from undifferentiated objects of the Solar System, which may retain signatures of primitive matter. Here, we present a comparative study between two CM chondrites Asuka 12236 and Paris, both considered among the most primitive in the carbonaceous chondrite meteorite collection.

Debris about asteroids: Where and how much? [PDF]
We summarize several recent findings on the size and shape of the region within which material can stably orbit an asteroid. If the asteroid (with assumed density 2.38 g/cu cm) circles the Sun at 2.55 AU, co-planar prograde material will remain trapped ...
