ESPRESSO high resolution transmission spectroscopy of WASP-76b
H. M. Tabernero, M. R. Zapatero Osorio, R. Allart +87
Aims. We report on ESPRESSO high-resolution transmission spectroscopic observations of two primary transits of the highly-irradiated, ultra-hot Jupiter-size planet WASP-76b. We inv…
ESPRESSO@VLT -- On-sky performance and first results
F. Pepe, S. Cristiani, R. Rebolo +97
ESPRESSO is the new high-resolution spectrograph of ESO's Very-Large Telescope (VLT). It was designed for ultra-high radial-velocity precision and extreme spectral fidelity with th…
A precise architecture characterization of the Men planetary system
M. Damasso, A. Sozzetti, C. Lovis +97
The bright star Men was chosen as the first target for a radial velocity follow-up to test the performance of ESPRESSO, the new high-resolution spectrograph at the ESO's Very-L…
Characterization of the K2-38 planetary system. Unraveling one of the densest planets known to date
B. Toledo-Padrón, C. Lovis, A. Suárez Mascareño +90
We characterized the transiting planetary system orbiting the G2V star K2-38 using the new-generation echelle spectrograph ESPRESSO. We carried out a photometric analysis of the av…
Revisiting Proxima with ESPRESSO
A. Suárez Mascareño, J. P. Faria, P. Figueira +88
We aim to confirm the presence of Proxima b using independent measurements obtained with the new ESPRESSO spectrograph, and refine the planetary parameters taking advantage of its…
Nightside condensation of iron in an ultra-hot giant exoplanet
David Ehrenreich, Christophe Lovis, Romain Allart +94
Ultra-hot giant exoplanets receive thousands of times Earth's insolation. Their high-temperature atmospheres (>2,000 K) are ideal laboratories for studying extreme planetary climat…
X-shooter, the new wide band intermediate resolution spectrograph at the ESO Very Large Telescope
Joel Vernet, H. Dekker, S. D'Odorico +87
X-shooter is the first 2nd generation instrument of the ESO Very Large Telescope(VLT). It is a very efficient, single-target, intermediate-resolution spectrograph that was installe…
The CODEX-ESPRESSO experiment: cosmic dynamics, fundamental physics, planets and much more..
S. Cristiani, G. Avila, P. Bonifacio +36
CODEX, a high resolution, super-stable spectrograph to be fed by the E-ELT, the most powerful telescope ever conceived, will for the first time provide the possibility of directly…
UVES observations of QSO 0000-2620: oxygen and zinc abundances in the Damped Ly-alpha galaxy at z_abs=3.3901
Paolo Molaro, Piercarlo Bonifacio, Miriam Centurion +4
Observations of the QSO 0000-2620 with UVES spectrograph at the 8.2m ESO KUEYEN telescope are used for abundance analysis of the damped Ly-alpha system at z_{abs}=3.3901. Several O…
