HD22496b: the first ESPRESSO standalone planet discovery
J. Lillo-Box, J. P. Faria, A. Suárez Mascareño +32
The ESPRESSO spectrograph is a new powerful tool to detect and characterize extrasolar planets. Its design allows unprecedented radial velocity precision (down to a few tens of cm/…
Fundamental physics with Espresso: Towards an accurate wavelength calibration for a precision test of the fine-structure constant
Tobias M. Schmidt, Paolo Molaro, Michael T. Murphy +56
Observations of metal absorption systems in the spectra of distant quasars allow to constrain a possible variation of the fine-structure constant throughout the history of the Univ…
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…
A Flexible and Modular Data Reduction Library for Fiber-fed Echelle Spectrographs
Danuta Sosnowska, Christophe Lovis, Pedro Figueira +4
Within the ESPRESSO project a new flexible data reduction library is being built. ESPRESSO, the Echelle SPectrograph for Rocky Exoplanets and Stable Spectral Observations is a fibe…
Evidence against the young hot-Jupiter around BD +20 1790
P. Figueira, M. Marmier, X. Bonfils +11
Context. The young active star BD +20 1790 is believed to host a substellar companion, revealed by radial-velocity measurements that detected the reflex motion induced on the paren…
