Neptunians and super-Earths in systems with “cold” Jupiters as test for planetary migration theories. The study: “The GAPS programme at TNG. XXIV. An eccentric Neptune-mass planet near the inner edge of the BD-11 4672 habitable zone” of D. Barbato (UniTo/OATo) and M. Pinamonti (OATo) recently appeared on A&A

The architecture of planetary systems is result from both the planet formation process and a complex mechanism of radial migration of planets. This has occurred also in the Solar System, whose final architecture resulted from the migration of the gaseous giants. In particular, the theories describing the formation and migration of super-Earths and Neptunian planets predict different configurations of the
