Composition of Near-Earth Asteroid (4179) Toutatis
Vishnu Reddy, Juan Andreas Sanchez, Michael Gaffey +3
Surface composition of near-Earth asteroid (4179) Toutatis is consistent with an undifferentiated L-chondrite composition. This is inconsistent with early observations that suggest…
Composition of Near-Earth Asteroid 2008 EV5: Potential target for Robotic and Human Exploration
Vishnu Reddy, Lucille Le Corre, Michael Hicks +5
We observed potentially hazardous asteroid (PHA) 2008 EV5 in the visible (0.30-0.92 microns) and near-IR (0.75-2.5 microns) wavelengths to determine its surface composition. This a…
Delivery of Dark Material to Vesta via Carbonaceous Chondritic Impacts
Vishnu Reddy, Lucille Le Corre, David P. O'Brien +22
NASA's Dawn spacecraft observations of asteroid (4) Vesta reveal a surface with the highest albedo and color variation of any asteroid we have observed so far. Terrains rich in low…
A general moment NRIXS approach to the determination of equilibrium Fe isotopic fractionation factors: application to goethite and jarosite
N. Dauphas, M. Roskosz, E. E. Alp +7
We measured the reduced partition function ratios for iron isotopes in goethite FeO(OH), potassium-jarosite KFe3(SO4)2(OH)6, and hydronium-jarosite (H3O)Fe3(SO4)2(OH)6, by Nuclear…
