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…
Measuring and characterizing the line profile of HARPS with a laser frequency comb
Fei Zhao, G. Lo Curto, L. Pasquini +13
Aims. We study the 2D spectral line profile of HARPS (High Accuracy Radial Velocity Planet Searcher), measuring its variation with position across the detector and with changing li…
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…
A crucial test for astronomical spectrograph calibration with frequency combs
Rafael A. Probst, Dinko Milaković, Borja Toledo-Padrón +23
Laser frequency combs (LFCs) are well on their way to becoming the next-generation calibration sources for precision astronomical spectroscopy. This development is considered key i…
