The GAPS programme at TNG XLIX. TOI-5398, the youngest compact multi-planet system composed of an inner sub-Neptune and an outer warm Saturn

G. Mantovan, L. Malavolta, S. Desidera +68

Short-period giant planets are frequently found to be solitary compared to other classes of exoplanets. Small inner companions to giant planets with 15 days are known…

The GAPS programme at TNG XLIII. A massive brown dwarf orbiting the active M dwarf TOI-5375

J. Maldonado, A. Petralia, G. Mantovan +23

Context. Massive substellar companions orbiting active low-mass stars are rare. They, however, offer an excellent opportunity to study the main mechanisms involved in the formation…

Cold Jupiters and improved masses in 38 Kepler and K2 small planet systems from 3661 HARPS-N radial velocities. No excess of cold Jupiters in small planet systems

A. S. Bonomo, X. Dumusque, A. Massa +31

The exoplanet population characterized by relatively short orbital periods ( d) around solar-type stars is dominated by super-Earths and sub-Neptunes. However, these planets…

HD 23472: A multi-planetary system with three super-Earths and two potential super-Mercuries

S. C. C. Barros, O. D. S. Demangeon, Y. Alibert +7

We report the characterisation of a multi-planetary system composed of five exoplanets orbiting the K-dwarf HD~23472 (TOI-174). In addition to the two super-Earths that were previo…

The GAPS programme at TNG XXXIV. Activity-rotation, flux-flux relationships, and active region evolution through stellar age

J. Maldonado, S. Colombo, A. Petralia +26

Active region evolution plays an important role in the generation and variability of magnetic fields on the surface of lower main-sequence stars. However, determining the lifetime…

Stellar parameters of early M dwarfs from ratios of spectral features at optical wavelengths

J. Maldonado, L. Affer, G. Micela +29

(Abridged) Low-mass stars have been recognised as promising targets in the search for rocky, small planets with the potential of supporting life. Doppler search programmes using hi…
