Fig. 2


Relative change in the bulk density of close-in planets, Δρ = 1 − ρ/ρs, as a function of the distance to the star r0. The red curve is relative to gaseous planets (hf = 1.5), while the blue one is relative to rocky planets (hf = 2.0). Both curves are obtained using expression (27) with i = 80°. The dots represent the planets listed in Table 1. For r0> 1.5 rR, the change is negligible when compared to the present observational errors in the density determination.
