Tracking the evolution of sub-Neptunes. II. The radius valley on gyrochronological ages
N. Greco, Nino Greco, Alessandro C. Lanzafame +9
The radius valley separating super-Earths from sub-Neptunes is understood as a signature of atmospheric mass loss, but the timescale over which it develops remains poorly constrain…
Tracking the evolution of sub-Neptunes. I. Gyrochronology of planet hosting stars
Alessandro C. Lanzafame, Vincenzo Drago, Nino Greco +3
Stellar age is fundamental for reconstructing planetary-system evolution but remains difficult to determine for unevolved main-sequence stars. Stellar rotation provides a sensitive…
Toward the Italian Astronomical Community's Contribution to HWO: Science, Technology, and Instrument Concepts
A. Fontana, F. Annibali, N. Antonietti +101
This paper summarizes the interest of the Italian astronomical community in the possible participation in the development of the Habitable Worlds Observatory (HWO). It is largely b…
The GAPS programme at TNG. LVII. TOI-5076b: A warm sub-Neptune planet orbiting a thin-to-thick-disk transition star in a wide binary system
M. Montalto, N. Greco, K. Biazzo +36
Aims. We report the confirmation of a new transiting exoplanet orbiting the star TOI-5076. Methods. We present our vetting procedure and follow-up observations which led to the con…
