A sub-Earth-mass planet orbiting Barnard's star
J. I. Gonzalez Hernandez, A. Suarez Mascareno, A. M. Silva +37
Barnard's star is a primary target within the ESPRESSO guaranteed time observations (GTO) as it is the second closest neighbour to our Sun after the Centauri stellar system. We…
Three super-Earths and a possible water world from TESS and ESPRESSO
M. J. Hobson, F. Bouchy, B. Lavie +51
Since 2018, the ESPRESSO spectrograph at the VLT has been hunting for planets in the Southern skies via the RV method. One of its goals is to follow up candidate planets from trans…
Probing the small scale structure of the Inter-Galactic Medium with ESPRESSO: spectroscopy of the lensed QSO UM673
Stefano Cristiani, Guido Cupani, Andrea Trost +20
The gravitationally lensed quasar J014516.6-094517 at z=2.719 has been observed with the ESPRESSO instrument at the ESO VLT to obtain high-fidelity spectra of the two images A and…
TESS and ESPRESSO discover a super-Earth and a mini-Neptune orbiting the K-dwarf TOI-238
A. Suárez Mascareño, V. M. Passegger, J. I. González Hernández +53
The number of super-Earth and mini-Neptune planet discoveries has increased significantly in the last two decades thanks to transit and radial velocity surveys. When it is possible…
Discovery of two warm mini-Neptunes with contrasting densities orbiting the young K3V star TOI-815
Angelica Psaridi, Hugh Osborn, François Bouchy +130
We present the discovery and characterization of two warm mini-Neptunes transiting the K3V star TOI-815 in a K-M binary system. Analysis of the spectra and rotation period reveal i…
The compact multi-planet system GJ 9827 revisited with ESPRESSO
V. M. Passegger, A. Suárez Mascareño, R. Allart +36
GJ 9827 is a bright, nearby K7V star orbited by two super-Earths and one mini-Neptune on close-in orbits. The system was first discovered using K2 data and then further characteriz…
