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…

Characterising TOI-732 b and c: New insights into the M-dwarf radius and density valley

A. Bonfanti, M. Brady, T. G. Wilson +88

TOI-732 is an M dwarf hosting two transiting planets that are located on the two opposite sides of the radius valley. By doubling the number of available space-based observations a…

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-…

CHEOPS observations of the HD 108236 planetary system: A fifth planet, improved ephemerides, and planetary radii

A. Bonfanti, L. Delrez, M. J. Hooton +106

The detection of a super-Earth and three mini-Neptunes transiting the bright ( = 9.2 mag) star HD 108236 (also known as TOI-1233) was recently reported on the basis of TESS and…

A resonant sextuplet of sub-Neptunes transiting the bright star HD 110067

R. Luque, H. P. Osborn, A. Leleu +149

Planets with radii between that of the Earth and Neptune (hereafter referred to as sub-Neptunes) are found in close-in orbits around more than half of all Sun-like stars. Yet, thei…

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…

Glancing through the debris disk: Photometric analysis of DE Boo with CHEOPS

Á. Boldog, Gy. M. Szabó, L. Kriskovics +76

DE Boo is a unique system, with an edge-on view through the debris disk around the star. The disk, which is analogous to the Kuiper belt in the Solar System, was reported to extend…

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…
