    Naphthalene Bisimides: on the Way to Ultrafast Opto-electronic Devices

    For core-substituted naphthalene bisimides and their dimers we observe ultrafast charge transfer and Resonance Energy Transfer processes that change their conduction properties. This makes them suitable candid...

    Exoplanets: The Road to Earth Twins

    Recent HARPS discoveries have demonstrated that very quiet stars exist, with intrinsic radial-velocity variations below 1 m s−1. These results allow us in particular to characterize an emerging new population of ...

    From ESPRESSO to CODEX

    CODEX and ESPRESSO are concepts for ultra-stable, high-resolution spectrographs at the E-ELT and VLT, respectively. Both instruments are well motivated by distinct sets of science drivers. However, ESPRESSO wi...

    Abundance Trends with Condensation Temperature in Planet-harbouring Stars: Hints of Pollution?

    We present the [X/H] trends as a function of the elemental condensation temperature Tc in 88 planet-host stars and in a volume-limited comparison sample of 33 dwarfs without detected planetary companions. We g...

    Transiting Planets: Follow the FLAMES...

    The identification of transiting planets candidates and their a posteriori confirmation and characterization by means of spectroscopic follow-up is allowing us to study the internal physics of these planets. H...

    Spectroscopic Parameters for a Sample of Metal-rich Solar-type Stars

    We present stellar parameters and metallicities for a sample of 64 high metal content stars not known to harbor any planet. This sample provides the reference for investigating new correlations between stars a...

    Planet Detection Around M Dwarfs: New Constraints on Planet Formation Models

    The dependence of planetary statistics on the physical conditions during the initial stages of the system (i.e. in the proto-planetary disk) represent an essential constraint on planetary formation mechanisms....

    High-resolution Spectroscopy of Faint Stars with Transiting Planets

    We present a series of studies based on high-resolution UVES/VLT spectroscopy of several faint stars for which a transit by a giant planet has been detected. The spectra were used to derive accurate stellar pa...
