    The 2008 Outburst of EX Lup—Silicate Crystals in Motion
    EX Lup is the prototype of the EXor class of eruptive young stars. These objects show optical outbursts which are thought to be related to runaway accretion...

    The Chemistry of the First Stars-Carbon in the Early Universe
    The very metal-poor (VMP; [Fe/H] < –2.0) and extremely metal-poor (EMP; [Fe/H] < –3.0) stars provide a direct view of Galactic chemical and dynamical evolution...

    The chemistry of the last major merger
    One prediction of ΛCDM is the existence of partially phase-mixed substructures from accreted dwarf galaxies in the Milky Way stellar halo. Substructure...

    The SUMO project: a survey of multiple populations in globular clusters
    The classical idea that globular clusters are the prototypes of simple stellar populations has been revolutionized in the last few years. Multiple sequences of...
