Planet density normalized by the expected density of an Earth-like composition (Dorn et al. 2017) versus the estimated iron-to-silicate mass fraction of the original protoplanetary disk (Santos et al. 2015, 2017) for the sample studied in Adibekyan et al. (2021) and for TOI-244 b considering the metal-poor and solar metallicity characterizations (see Sect. 3.2). The Earth and Mercury are indicated with their respective symbols in black. All error bars show 1σ uncertainties.
