A stellar companion within the fiberis such a possible noise source.Aims.With this work we aim at characterizing the… 

Impact of micro-telluric lines on precise radial velocities and its correction

Context: In the near future, new instruments such as ESPRESSO will arrive, allowing us to reach a precision in radial-velocity measurements on the order of 10 cm/s. At this level of precision,

Catalog for the ESPRESSO blind radial velocity exoplanet survey

Aims. One of the main scientific drivers for ESPRESSO, Échelle SPectrograph, is the detection and characterization of Earth-class exoplanets. With this goal in mind, the ESPRESSO guaranteed time

PASTIS: Bayesian extrasolar planet validation II. Constraining exoplanet blend scenarios using spectroscopic diagnoses

The statistical validation of transiting exoplanets proved to be an e cient technique to secure the nature of small exoplanet signals which cannot be established by purely spectroscopic means.


Context. ESPRESSO is the new high-resolution spectrograph of ESO’s Very Large Telescope (VLT). It was designed for ultra-high radial-velocity (RV) precision and extreme spectral fidelity with the aim

Solving the Catalogue Cross-Match Problem in the Galactic Plane

1st Supervisor: Prof. Tim Naylor 2nd Supervisor: Dr Jennifer Hatchell In this thesis the cross-matching problem is considered. One of the most fundamental processes in astrophysics, the

The HARPS search for southern extra-solar planets XXXIX. HD175607, the most metal-poor G dwarf with an orbiting sub-Neptune

Context. The presence of a small-mass planet (M-p \textless 0.1 M-Jup) seems, to date, not to depend on metallicity, however, theoretical simulations have shown that stars with subsolar metallicities

Recovering the colour-dependent albedo of exoplanets with high-resolution spectroscopy: from ESPRESSO to the ELT

The characterization of planetary atmospheres is a daunting task, pushing current observing facilities to their limits. The next generation of high-resolution spectrographs mounted on large

K2-280 b – a low density warm sub-Saturn around a mildly evolved star

We present an independent discovery and detailed characterization of K2-280 b, a transiting low density warm sub-Saturn in a 19.9-d moderately eccentric orbit (e = $0.35_{-0.04}^{+0.05}$ ) from K2

Characterizing the atmosphere of exoplanets using high-resolution spectroscopy

The discovery of planets around other stars is one of the greatest scientific discoveries of the 20th century. Nowadays, exoplanetology is one of the fields in Astronomy that generates most interest,

The GAPS Programme with HARPS-N@TNG VI: The Curious Case of TrES-4b

We revisit the TrES-4 system parameters based on high-precision HARPS-N radial-velocity measurements and new photometric light curves. A combined spectroscopic and photometric analysis allows us to



Planetary detection limits taking into account stellar noise - II. Effect of stellar spot groups on radial-velocities

Context. The detection of small mass planets with the radial-velocity technique is now confronted with the interference of stellar noise. HARPS can now reach a precision below the meter-per-second,

No planet for HD 166435

The G0 V star HD 166435 has been observed by the ber-fed spectrograph ELODIE as one of the targets in the large extra-solar planet survey that we are conducting at the Observatory of Haute-Provence.

Evidence against the young hot-Jupiter around BD +20 1790

Context. The young active star BD +201790 has been inferred to host a substellar companion from radial-velocity measurements that detected the reflex motion induced on the parent star. Aims. We


We present the results of an extensive high-resolution imaging survey of M-dwarf multiplicity using the Lucky Imaging technique. The survey made use of the AstraLux Norte camera at the Calar Alto 2.2

TW Hydrae: evidence of stellar spots instead of a Hot Jupiter

Context. TW Hya is a classical T Tauri star that shows significant radial-velocity variations in the optical regime. These variations have been attributed to a 10 MJup planet orbiting the star at


We present the discovery of a hot Jupiter transiting an F star in a close visual (0.″3 sky projected angular separation) binary system. The dilution of the host star's light by the nearly equal

Planetary detection limits taking into account stellar noise - I. Observational strategies to reduce stellar oscillation and granulation effects

Context. Stellar noise produced by oscillations, granulation phenomena (granulation, mesogranulation, and supergranulation), and activity affects radial velocity measurements. The signature of the

The CORALIE survey for southern extra-solar planets - IX. A 1.3-day period brown dwarf disguised as a planet

In this article we present the case of HD 41004 AB, a system composed of a K0V star and a 3.7-mag fainter M-dwarf companion. We have obtained 86 CORALIE spectra of this system with the goal of

A synthetic view on structure and evolution of the Milky Way

Since the Hipparcos mission and recent large scale surveys in the optical and the near-infrared, new constraints have been obtained on the structure and evolution history of the Milky Way. The


We present new spectroscopic and photometric observations of the transiting exoplanetary system WASP-3. Spectra obtained during two separate transits exhibit the Rossiter–McLaughlin (RM) effect and
