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…
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/…
Warm terrestrial planet with half the mass of Venus transiting a nearby star
Olivier D. S. Demangeon, M. R. Zapatero Osorio, Y. Alibert +42
The advent of a new generation of radial velocity instruments has allowed us to break the one Earth-mass barrier. We report a new milestone in this context with the detection of th…
On-sky measurements of atmospheric dispersion: II. Atmospheric models characterization
B. Wehbe., A. Cabral, L. Sbordone +1
Differential atmospheric dispersion is a wavelength-dependent effect introduced by Earth's atmosphere that affects astronomical observations performed using ground-based telescopes…
A sub-Neptune and a non-transiting Neptune-mass companion unveiled by ESPRESSO around the bright late-F dwarf HD 5278 (TOI-130)
A. Sozzetti, M. Damasso, A. S. Bonomo +45
[Abridged] We exploit the extreme radial velocity (RV) precision of the ultra-stable echelle spectrograph ESPRESSO on the VLT to unveil the physical properties of the transiting su…
