The GAPS Programme with HARPS-N at TNG LXXVII. Occurrence rates of small close-in planets in the presence of cold Jupiters
A. Ruggieri, S. Desidera, M. Pinamonti +18
The paper compiles a homogeneous sample of 137 stars with cold Jupiters and uses radial‑velocity data, including new HARPS‑N observations, to measure how often inner small planets…
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 35-Myr old infant planet TOI-837 b has a mildly misaligned orbit
G. Mantovan, L. Malavolta, F. Marzari +6
The measurement of the spin-orbit obliquity, that is, the angle between the orbital axis of a planet and the stellar spin axis, provides crucial insights into how planets form and…
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 ($…
The GAPS Programme at TNG. LXXIII. Confirmation of the hot sub-Neptune TOI-4602 b (HD 25295 b), a key target for future atmospheric characterization
C. Di Maio, S. Benatti, D. Locci +25
Precise mass and radius measurements of small, transitional exoplanets, such as super-Earths and sub-Neptunes, are essential to constrain their bulk density and formation history,…
The GAPS programme at TNG LXXI. A sub-Neptune suitable for atmospheric characterization in a multiplanet and mutually inclined system orbiting the bright K dwarf TOI-5789 (HIP 99452)
A. S. Bonomo, L. Naponiello, A. Sozzetti +37
Sub-Neptunes with planetary radii of are the most common planets around solar-type stars in short-period ( d) orbits. It is still unclear, howe…
