    • How do secondary iron enrichments form within basaltic eucrites? An experimental approach 

      Rombeck, Stella; Vollmer, ChristianORCIDiD; Roszjar, Julia; Sarafian, Adam R.ORCIDiD; Klemme, Stephan (Meteoritics & Planetary Science, 2021-05-02)
      Some basaltic eucrites and basaltic lithologies in howardites derived from the asteroid 4 Vesta exhibit unusual secondary veinlet textures consisting mostly of fayalitic olivine and Fe‐enrichments within pyroxenes. Recent ...
    • Influence of Volatiles on Mass Wasting Processes on Vesta and Ceres 

      Parekh, R.ORCIDiD; Otto, K. A.ORCIDiD; Jaumann, R.ORCIDiD; Matz, K. D.ORCIDiD; Roatsch, T.ORCIDiD; Kersten, E.ORCIDiD; Elgner, S.ORCIDiD; Raymond, C.ORCIDiD (Journal of Geophysical Research: Planets, 2021-03-19)
      We have analyzed mass wasting features, their distribution and deposit geometry on the two largest main asteroid belt objects—protoplanet Vesta and dwarf planet Ceres—and compared their geomorphology and mobility. Both ...
    • The Boulder Population of Asteroid 4 Vesta: Size‐Frequency Distribution and Survival Time 

      Schröder, Stefan E.ORCIDiD; Carsenty, UriORCIDiD; Hauber, ErnstORCIDiD; Schulzeck, Franziska; Raymond, Carol A.ORCIDiD; Russell, Christopher T.ORCIDiD (Earth and Space Science, 2021-01-26)
      Dawn's framing camera observed boulders on the surface of Vesta when the spacecraftwas in its lowest orbit (Low Altitude Mapping Orbit, LAMO). We identified, measured, and mapped boulders in LAMO images, which have a scale ...
