A transiting giant planet with a temperature between 250 K and 430 K
About 70 of the more than 400 known extrasolar planets transit their central star, making it possible to observe their atmospheres and determine various key parameters. The transiting extra-solar planets so fa...

An orbital period of 0.94 days for the hot-Jupiter planet WASP-18b
'Hot Jupiter' extrasolar planets are thought to have formed at some distance from their host stars and to have migrated inwards at a later date. These planets provide new perspectives on the evolution of plane...

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...

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....

Pushing Down the Limits of the Radial Velocity Technique
We present results from the first three years of operations of the HARPS spectrograph installed on the ESO-3.6m telescope at La Silla Observatory, Chile. This instrument, primarily built to detect extrasolar p...

Extrasolar Planets in Double and Multiple Stellar Systems
About 60% of G and K dwarfs belong to double or multiple stellar systems, making these a common environment in which planets may form. Despite this, close binaries have often been rejected from radial-velocity...

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...

Oxygen in Metal-Rich Stars: Abundances from [O I] 6300, OI 7771–5 and Near-UV OH
Oxygen abundances of a large number of metal-rich stars, with and without known planets, were derived from the forbidden line [O I] 6300 Å, the OI 7771–5 Å triplet and from near-UV OH lines. Non-LTE correction...

An extended upper atmosphere around the extrasolar planet HD209458b
The planet in the system HD209458 is the first one for which repeated transits across the stellar disk have been observed1,2. Together with radial velocity measurements3, this has led to a determination of the pl...
