Abstract: Abstract The 26 Al- 26 Mg short-lived chronometer has been widely used for dating ancient objects in studying the early Solar System. Here, we use this chronometer to investigate and refine the geological history of… read more here.

Abstract: Abstract We present near-infrared (0.78–2.45 µm) reflectance spectra for nine middle and outer main belt ( a > 2.5 AU) basaltic asteroids. Three of these objects are spectrally distinct from all classifications in the Bus-DeMeo system… read more here.

DOI: 10.1016/j.icarus.2020.113718
Abstract: Abstract A major goal of the Dawn mission to Vesta was to test and refine current models of the asteroid's formation by characterizing the distribution of mineral components on its surface. Detection of the mineral… read more here.
