These classes are generally expected to be variations within a compositional continuum. Recently, however, Luque & Pall\\'e observed that potentially Earth-like planets around M dwarfs are separated from a lower-density population by a density gap. Meanwhile, the results of Adibekyan et al. hint that iron-rich planets around FGK stars are also a distinct population. It there","authors_text":"B. S. Gaudi, C. T. Unterborn, J. A. Johnson, J. G.
