    Spectroscopy of B-type asteroids: Subgroups and meteorite analogs
    B-type asteroids have a negative slope from ˜0.5 to ˜1.1 μm and beyond. What causes this? Visible to near-infrared reflectance spectra (0.4-2.5 μm) are...

    Spins and shapes of basaltic asteroids and the missing mantle problem
    Basaltic V-type asteroids are common in the inner part of the Main Asteroid Belt and much less abundant in the mid and outer parts. They are of scientific...
