Influence of Giant Planets near the 5:2 Resonance in the Habitable Zone of Sun-Like Stars (original) (raw)
From the nearly 190 planets that have been discovered so far we can distinguish the following types of HZs from the dynamicals point of view: 1) The solar-system type (SST) - where the HZ is between the host-star and the detected giant planet. 2) The hot-Jupiter type (HJT) for a close-in giant planet, the HZ is outside its orbit. 3) The giant planet type (GPT) - when the detected planet moves in the HZ. In this case we can only expect "habitable moons" or "habitable trojan-like planets". 4) Furthermore in multi-planet systems there will be combinations of these 3 types. But even if a planet will be detected in the HZ, it has to be verified if it can be considered as habitable planet. An important contribution from the dynamical point of view is to examine the long-term dynamical behavior of the orbital motion in this region, which obviously depends on the motion of the giant planets in the systems. Motivated by the fact, that in some of the discovered multi-plane...
