TOI-512: Super-Earth transiting a K-type star discovered by TESS and ESPRESSO
J. Rodrigues, S. C. Barros, N. C. Santos +38
One of the goals of the ESPRESSO guaranteed time observations (GTOs) at the ESO 8.2m telescope is to follow up on candidate planets from transit surveys such as the TESS mission. H…
ESPRESSO reveals blueshifted neutral iron emission lines on the dayside of WASP-76 b
A. R. Costa Silva, O. D. S. Demangeon, N. C. Santos +34
Ultra hot Jupiters (gas giants, Teq>2000 K) are intriguing exoplanets due to their extreme atmospheres. Their torrid daysides can be characterised using ground-based high-resolutio…
The atmospheric composition of the ultra-hot Jupiter WASP-178 b observed with ESPRESSO
Y. C. Damasceno, J. V. Seidel, B. Prinoth +25
We search for atmospheric constituents for the UHJ WASP-178 b with two ESPRESSO transits using the narrow-band and cross-correlation techniques, focusing on the detections of NaI,…
Photo-dynamical characterisation of the TOI-178 resonant chain
A. Leleu, J. -B. Delisle, L. Delrez +104
The TOI-178 system consists of a nearby late K-dwarf transited by six planets in the super-Earth to mini-Neptune regime, with radii ranging from 1.2 to 2.9 earth radius and orbital…
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…
An ESPRESSO view of HD 189733 system. Broadband transmission spectrum, differential rotation, and system architecture
E. Cristo, E. Esparza Borges, N. C. Santos +25
The development of state-of-the-art spectrographs has ushered in a new era in the detection and characterization of exoplanetary systems. Our objective is to utilize the high-resol…
Revisiting Proxima with ESPRESSO
A. Suárez Mascareño, J. P. Faria, P. Figueira +88
We aim to confirm the presence of Proxima b using independent measurements obtained with the new ESPRESSO spectrograph, and refine the planetary parameters taking advantage of its…
The GAPS Programme with HARPS-N at TNG XVIII. Two new giant planets around the metal-poor stars HD 220197 and HD 233832
D. Barbato, A. Sozzetti, K. Biazzo +40
Statistical studies of exoplanets have shown that giant planets are more commonly hosted by metal-rich dwarf stars than low-metallicity ones, while such a correlation is not eviden…
The GAPS Programme with HARPS-N@TNG VI: The Curious Case of TrES-4b
A. Sozzetti, A. S. Bonomo, K. Biazzo +38
We revisit the TrES-4 system parameters based on high-precision HARPS-N radial-velocity measurements and new photometric light curves. A combined spectroscopic and photometric anal…
The GAPS Programme with HARPS-N@TNG II: No giant planets around the metal-poor star HIP 11952
S. Desidera, A. Sozzetti, A. S. Bonomo +37
In the context of the program Global Architecture of Planetary Systems (GAPS), we have performed radial velocity monitoring of the metal-poor star HIP 11952 on 35 nights over about…
