| Abstract | We present a new statistical analysis done via principal component analysis followed by hierarchical clustering analysis. We report the definition of five robust groups of planets. For instance, we were able to divide the hot Jupiters into two main groups, on the basis of their star masses and metallicities. Moreover, for some groups, we find strong correlations between metallicity and semi-major axis and eccentricity. |
