High-resolution transmission spectroscopy of KELT-18b Metastable helium detection at 1083 nm
M. Chella, M. Monticelli, F. Biassoni +5
We present the first high-resolution transmission spectroscopy of the ultrahot Jupiter KELT-18b, probing its escaping atmosphere by analyzing a single transit obtained with the CAR…
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 LXXVIII. Phase-resolved detection of multiple atomic species in the atmosphere of KELT-20b/MASCARA-2b
F. Biassoni, F. Borsa, L. Fossati +15
Among the different classes of exoplanets, ultra-hot Jupiters represent prime laboratories for atmospheric characterisation. With an equilibrium temperature of ~2300 K, KELT-20b/MA…
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…
A tidally detached super Neptune on a strongly misaligned retrograde orbit
G. Mantovan, L. Malavolta, A. F. Lanza +18
The obliquity between a planet's orbital axis and its host star's spin axis provides crucial insights into planetary formation and migration. Planets with scaled semi-major axes ($…
