The GAPS programme at TNG LXXXII. The first atmospheric investigation of the gas giant WASP-13b at high resolution with GIARPS
D. Sicilia, M. Basilicata, G. Guilluy +17
Low-density transiting gas giant exoplanets are key benchmarks for atmospheric studies. Despite their large-scale heights, many of them remain poorly characterised. We present the…
Toward the Italian Astronomical Community's Contribution to HWO: Science, Technology, and Instrument Concepts
A. Fontana, F. Annibali, N. Antonietti +101
This paper summarizes the interest of the Italian astronomical community in the possible participation in the development of the Habitable Worlds Observatory (HWO). It is largely b…
The GAPS programme at TNG LXXIX. New mass constraints for the infant planets in the V1298 Tau system through a long-term radial velocity monitoring with HARPS-N
M. Damasso, P. Leonardi, L. Borsato +26
We aim to constrain the dynamical masses of the four confirmed transiting planets orbiting the infant ( Myr) star V1298,Tau (orbital periods 24.1 d, 8.2…
The GAPS programme at TNG LXXV. Validating and confirming Gaia substellar astrometric candidates with HARPS-N
D. Barbato, M. Pinamonti, A. Sozzetti +22
The astrometric measurements provided by the Gaia space mission represent a key advancement in the search and characterization of exoplanets, helping in particular to solve the mas…
The GAPS programme at TNG LXX. HD 128717 B/Gaia-6 B: a long-period eccentric low-mass brown dwarf from astrometry and radial velocities
M. Pinamonti, A. Sozzetti, D. Barbato +24
The transition regime between giant planets (GPs) and brown dwarfs (BDs) is still an open subject of study in exoplanetary science. A complete understanding of the population of lo…
Mass determination of the three long-period Neptune- and sub-Neptune-sized planets transiting TOI-282
A. Barone, F. Rodler, D. Gandolfi +16
TOI-282 is a bright (V=9.38) F8 main-sequence star known to host three transiting long-period (=22.9 d, =56.0 d, and =84.3 d) small ( 2-4 ) p…
The GAPS Programme at TNG. LXIX.The Dayside of WASP-76b revealed by GIANO-B, HARPS-N and ESPRESSO: Evidence for Three-Dimensional Atmospheric Effects
G. Guilluy, P. Giacobbe, M. Brogi +22
The study of the atmosphere of ultra-hot Jupiters (UHJs) with equilibrium temperature 2000 K provides valuable insights into atmospheric physics under such extreme conditions…
The GAPS Programme at TNG LXVII. Detection of water and preliminary characterisation of the atmospheres of the two hot Jupiters KELT-8 b and KELT-23 Ab
M. Basilicata, P. Giacobbe, M. Brogi +22
Expanding the number of hot giant planets with atmospheric characterisation can improve our understanding of their atmospheres as well as their formation and evolution mechanisms.…
Time Resolved Absorption of Six Chemical Species With MAROON-X Points to Strong Drag in the Ultra Hot Jupiter TOI-1518 b
A. Simonnin, V. Parmentier, J. P. Wardenier +27
Wind dynamics play a pivotal role in governing transport processes within planetary atmospheres, influencing atmospheric chemistry, cloud formation, and the overall energy budget.…
The GAPS programme at TNG: TBD. Studies of atmospheric FeII winds in ultra-hot Jupiters KELT-9b and KELT-20b using HARPS-N spectrograph
M. Stangret, L. Fossati, M. C. D'Arpa +21
Ultra-hot Jupiters (UHJs) are gas giant planets orbiting close to their host star, with equilibrium temperatures exceeding 2000 K, and among the most studied planets in terms of th…
The GAPS programme at TNG LX Atmospheric characterisation of KELT-9 b via single-line analysis: Detection of six H I Balmer lines, Na I, Ca I, Ca II, Fe I, Fe II, Mg I, Ti II, Sc II, and Cr II
M. C. D'Arpa, A. Saba, F. Borsa +27
We analysed six primary transits of the ultra-hot Jupiter KELT-9,b obtained with the HARPS-N high-resolution spectrograph in the context of the Global Architecture of Planetary Sys…
The GAPS Programme at TNG LV. Multiple molecular species in the atmosphere of HAT-P-11 b and review of the HAT-P-11 planetary system
M. Basilicata, P. Giacobbe, A. S. Bonomo +29
The atmospheric characterisation of hot and warm Neptune-size exoplanets is challenging due to their small radius and atmospheric scale height. The warm-Neptune HAT-P-11b is a rema…

F. Borsa, M. Rainer, A. S. Bonomo +40
In the framework of the GAPS project, we observed the planet-hosting star KELT-9 (A-type star, VsinI110 km/s) with the HARPS-N spectrograph at the TNG. In this work we analys…
