By using the Exocatalogue one can determine the stability of hypothetical Earth-like planets in certain exoplanetary systems. The use of the Exocatalogue we present through an example:

Stability map for μ = 0.005.

Let us consider the case of the system around HD10697, where a₁=2.13 AU, e₁=0.11, μ = 0.0055. In order to study the possible regions of stability of terrestrial planets in this system, we chose the stability map calculated for μ=0.005 and for inner orbits. Then the stability of a small planet (starting with e=0) can be promptly determined along the line e₁=0.11. One can see that for smaller semi-major axes a<0.33·a₁=0.729 AU the phase space is very stable. Having a>0.33·a₁=0.729 AU, several mean motion resonances appear, among them the most important are the 5:1, the 4:1, the 3:1, and the 2:1 respectively. For a>0.73xa₁=1.55 AU a strongly chaotic region appears.

Stability map for μ = 0.001.

The habitable zone of this system is between 0.85-1.65 AU. Thus in the corresponding stability map the scaled habitable zone is marked (as an elongated rectangle in horizontal direction) between 0.85/a₁ = 0.39 and 1.65/a₁=0.77. One can see that the inner part of the habitable zone contains ordered regions but also the stripes of certain mean motion resonances are present. The outer part of the habitable zone is in the strongly chaotic region.
