Data analysis on the extrasolar planets using robust clustering.

Abstract (from CDS):

We use both the conventional and more recently developed methods of cluster analysis to study the data of extrasolar planets (exoplanets). Using the data set with planetary mass M, orbital period P and orbital eccentricity e, we investigate the possible clustering in the lnM, lnP, lnP-lnM, e and ln P-e spaces. There are two main implications: (1) mass distribution is continuous, and (2) orbital population could be classified into three clusters, which correspond to the exoplanets in the regimes of tidal, ongoing tidal and disc interaction, respectively.
