    The Bowen Survey; detecting donor star signatures in low mass X-ray binaries
    For most persistent low mass X-ray binaries (LMXBs) and transients in outbursts the optical emission is dominated by reprocessing of the X-rays in the outer...

    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 CoRoT satellite and its surprising exoplanets
    Up to now more than 400 extrasolar planets have been discovered, about 60 of them are transiting. Transiting extra-solar planets are particularly interesting...

    The Cosmic History of Black Hole Growth
    It is now clear that supermassive black holes (M>1e6 Msun) live in the center of most (all) galaxies, including our own Milky Way. Furthermore, the energy...
