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…
Cross-correlation transmission spectroscopy of ultra-hot Jupiters WASP-189b, HAT-P-57b, KELT-17b, and KELT-21b with GIANO-B
P. Meni-Gallardo, J. Orell-Miquel, Gareb Fernández-RodrÃguez +6
Since the discovery of the first exoplanet, significant efforts have been made to characterise their atmospheres. Ultra-hot Jupiters (UHJs) are of particular interest due to their…
Hidden worlds: a non-transiting candidate planet in the Neptunian desert around the solar-type pulsator KIC 9139163
Sylvain N. Breton, Achrène Dyrek, Carlos Allende Prieto +16
Close-in substellar companions experience strong tidal and magnetic interactions with their host stars and are therefore subject to fast orbital evolution. The solar-type pulsator…
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…
Two warm sub-Saturn mass planets identified from the TESS Full Frame Images
Felipe I. Rojas, Rafael Brahm, Andrés Jordán +47
Context. Characterization of warm giants is crucial to constrain giant planet formation and evolution. Measuring the mass and radius of these planets, combined with their moderated…
