Two mini-Neptuns in orbital resonance around TOI-1803 discovered and described in the paper: “A joint effort to discover and characterize two resonant mini Neptunes around TOI-1803 with TESS, HARPS-N and CHEOPS” of T. Zingales (UniPd/INAF-OAPd))

With over 2.600 exoplanets discovered, NASA’s Kepler satellite holds the record for the mission with the highest number of exoplanets found. The Kepler mission continued with the Kepler/K2 extension, redefined after technical failures prevented the telescope from maintaining its pointing. Among the many discoveries made possible by Kepler/K2 is evidence that one of the most common types of planets in

On the fequency of sub-neptunians in planetary systems with giant planets. The study: “The GAPS programme at TNG. XLVI. Deep search for low-mass planets in late-dwarf systems hosting cold Jupiters” of M. Pinamonti (INAF – OATo) appeared on A&A

The two giant planets of the Solar System, Jupiter and Saturn, played an important role in shaping the properties and architecture of the inner solar system. This may be a quite general rule. The presence of giant planets, for instance, can be responsible for a less effective migration of solids and gas toward the inner part of planetary systems, inhibiting
