WASP-128b: a transiting brown dwarf in the dynamical-tide regime (2018)
Journal Article

Massive companions in close orbits around G dwarfs are thought to undergo rapid orbital decay due to runaway tidal dissipation. We report here the discovery of WASP-128b, a brown dwarf discovered by the WASP survey transiting a G0V host on a 2.2 d or...

Context. Atmospheric properties of F-, G- and K-type stars can be measured by spectral model fitting or with the analysis of equivalent width (EW) measurements. These methods require data with good signal-to-noise ratios (S/Ns) and reliable continuum... Read More about The atmospheric parameters of FGK stars using wavelet analysis of CORALIE spectra.

An absolute sodium abundance for a cloud-free 'hot Saturn' exoplanet. (2018)

Broad absorption signatures from alkali metals, such as the sodium (Na I) and potassium (K I) resonance doublets, have long been predicted in the optical atmospheric spectra of cloud-free irradiated gas giant exoplanets1-3. However, observations have... Read More about An absolute sodium abundance for a cloud-free 'hot Saturn' exoplanet..

To investigate the origin of the features discovered in the exoplanet population, the knowledge of exoplanets mass and radius with a good precision (less than or similar to 10%) is essential. To achieve this purpose the discovery of transiting exopla...
