ANDES, the high resolution spectrograph for the ELT: science goals, project overview and future developments
A. Marconi, M. Abreu, V. Adibekyan +286
The first generation of ELT instruments includes an optical-infrared high-resolution spectrograph, indicated as ELT-HIRES and recently christened ANDES (ArmazoNes high Dispersion E…
ANDES, the high-resolution spectrograph for the ELT: RIZ Spectrograph preliminary design
Bruno Chazelas, Yevgeniy Ivanisenko, Audrey Lanotte +44
We present here the preliminary design of the RIZ module, one of the visible spectrographs of the ANDES instrument 1. It is a fiber-fed high-resolution, high-stability spectrograph…
Fundamental physics with ESPRESSO: Precise limit on variations in the fine-structure constant towards the bright quasar HE 05154414
Michael T. Murphy, Paolo Molaro, Ana C. O. Leite +40
The strong intervening absorption system at redshift 1.15 towards the very bright quasar HE 05154414 is the most studied absorber for measuring possible cosmological variations…
HIRES, the high-resolution spectrograph for the ELT
Alessandro Marconi, Manuel Abreu, Vardan Adibekyan +99
HIRES will be the high-resolution spectrograph of the European Extremely Large Telescope at optical and near-infrared wavelengths. It consists of three fibre-fed spectrographs prov…
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…
Atmospheric Rossiter-McLaughlin effect and transmission spectroscopy of WASP-121b with ESPRESSO
F. Borsa, R. Allart, N. Casasayas-Barris +41
WASP-121b is one of the most studied Ultra-hot Jupiters: many recent analyses of its atmosphere report interesting features at different wavelength ranges. In this paper we analyze…
WASP-127b: A misaligned planet with a partly cloudy atmosphere and tenuous sodium signature seen by ESPRESSO
R. Allart, L. Pino, C. Lovis +45
The study of exoplanet atmospheres is essential to understand the formation, evolution and composition of exoplanets. The transmission spectroscopy technique is playing a significa…
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…
Rotational and rotational-vibrational Raman spectroscopy of air to characterize astronomical spectrographs
F. P. A. Vogt, F. Kerber, A. Mehner +14
Raman scattering enables unforeseen uses for the laser guide-star system of the Very Large Telescope. Here, we present the observation of one up-link sodium laser beam acquired wit…
ESPRESSO: The next European exoplanet hunter
F. Pepe, P. Molaro, S. Cristiani +55
The acronym ESPRESSO stems for Echelle SPectrograph for Rocky Exoplanets and Stable Spectroscopic Observations; this instrument will be the next VLT high resolution spectrograph. T…
