PublicationThe GAPS Programme at TNG. XXXIII. HARPS-N detects multiple atomic species in emission from the dayside of KELT-20b
The detection of lines in emission in planetary atmospheres provides direct evidence of temperature inversion. We confirm the trend of ultra-hot Jupiters...

PublicationThe GAPS Programme at TNG. XXXVII. A precise density measurement of the young ultra-short period planet TOI-1807 b
Context. Great strides have been made in recent years in the understanding of the mechanisms involved in the formation and evolution of planetary systems...

PublicationThe GAPS programme with HARPS-N at TNG. I. Observations of the Rossiter-McLaughlin effect and characterisation of the transiting system Qatar-1
Context. Our understanding of the formation and evolution of planetary systems is still fragmentary because most of the current data provide limited information...

PublicationThe GAPS programme with HARPS-N at TNG. II. No giant planets around the metal-poor star HIP 11952
In the context of the programme Global Architecture of Planetary Systems (GAPS), we have performed radial velocity monitoring of the metal-poor star HIP 11952...

PublicationThe GAPS Programme with HARPS-N at TNG. III: The retrograde orbit of HAT-P-18b
The measurement of the Rossiter-McLaughlin effect for transiting exoplanets places constraints on the orientation of the orbital axis with respect to the...

PublicationThe GAPS programme with HARPS-N at TNG. IV. A planetary system around XO-2S
We performed an intensive radial velocity monitoring of XO-2S, the wide companion of the transiting planet-host XO-2N, using HARPS-N at TNG in the framework of...

PublicationThe GAPS programme with HARPS-N at TNG. IX. The multi-planet system KELT-6: Detection of the planet KELT-6 c and measurement of the Rossiter-McLaughlin effect for KELT-6 b
Aims: For more than 1.5 years we spectroscopically monitored the star KELT-6 (BD+31 2447), which is known to host the transiting hot-Saturn KELT-6 b, because a...

PublicationThe GAPS programme with HARPS-N at TNG. V. A comprehensive analysis of the XO-2 stellar and planetary systems
Aims: XO-2 is the first confirmed wide stellar binary system where the almost twin components XO-2N and XO-2S have planets, and it is a peculiar laboratory in...
