The GAPS Programme at TNG. LXXX. Characterisation of the 400 Myr old multi-planet system K2-233
V. Fardella, S. Benatti, R. Spinelli +27
Understanding exoplanet physical properties is crucial for characterising their atmospheres and internal composition. Precise planetary masses are essential for constraining bulk d…
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
Context. The architecture of our Solar System, with inner small planets (ISPs) and outer giants, may or may not be common. Understanding whether a correlation exists between ISPs a…
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…
SaNDi-SHoP: Searching for Satellites'N'Disks with a Star-Hopping Program I. Analysis of the close surroundings of DI companions
Cecilia Lazzoni, Alice Zurlo, Silvano Desidera +6
We aim to search for satellites and circumplanetary or circumsubstellar disks around directly imaged substellar companions, exploring their immediate environment to constrain the c…
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…
The GAPS Programme at TNG LXVIII. Characterization of the outer substellar companion around HD 72659 with a multi-technique approach
A. Ruggieri, A. Sozzetti, S. Desidera +23
Before discovering the first exoplanets, the Radial Velocity (RV) method had been used for decades to discover binary stars. Despite significant advancements in this technique, it…
A study of the frequency and characteristics of stellar companions and Jupiter-like planets in nearby open clusters
R. Gratton, M. Bonavita, D. Mesa +9
Observations of companions of solar-type stars in nearby young moving groups (NYMGs) show that they split into two groups: stellar and brown dwarf companions (mass ratio )…
A multi-technique detection of an eccentric giant planet around accelerating star HD 57625
D. Barbato, D. Mesa, V. D'Orazi +42
The synergy between different detection methods is a key asset in exoplanetology, allowing for both precise characterization of detected exoplanets and robust constraints even in t…
Deep imaging of three accelerating stars using SHARK-NIR and LMIRCam at LBT
D. Mesa, R. Gratton, V. D'Orazi +29
The combination of detection techniques enhances our ability to identify companions orbiting nearby stars. We employed high-contrast imaging to constrain mass and separation of pos…
Stellar companions and Jupiter-like planets in young associations
R. Gratton, M. Bonavita, D. Mesa +9
Recently, combining high-contrast imaging and space astrometry we found that Jupiter-like (JL) planets are frequent in the beta Pic moving group (BPMG) around those stars where the…
Detection of the tidal deformation of WASP-103b at with CHEOPS
S. C. C. Barros, B. Akinsanm, G. Boué +5
WASP-103b is the exoplanet with the highest expected deformation signature in its transit light curve and one of the shortest expected spiral-in times. Measuring the tidal deformat…
