A definition for giant planets based on the mass-density relationship.

HATZES A.P. and RAUER H.

Abstract (from CDS):

We present the mass-density relationship (log M - log ρ) for objects with masses ranging from planets (M ≈ 0.01 M_Jup) to stars (M > 0.08 M_☉). This relationship shows three distinct regions separated by a change in slope in the log M - log ρ plane. In particular, objects with masses in the range 0.3 M_Jup-60 M_Jup follow a tight linear relationship with no distinguishing feature to separate the low-mass end (giant planets) from the high-mass end (brown dwarfs). We propose a new definition of giant planets simply based on changes in the slope of the log M versus log ρ relationship. By this criterion, objects with masses less than ≈0.3 M_Jupare low-mass planets, either icy or rocky. Giant planets cover the mass range 0.3 M_Jup-60 M_Jup. Analogous to the stellar main sequence, objects on the upper end of the giant planet sequence (brown dwarfs) can simply be referred to as ''high-mass giant planets,'' while planets with masses near that of Jupiter can be called ''low-mass giant planets.''
