Distribution of the mass of planets around M-dwarf stars as a function of their orbital semi-major axes obtained from the population synthesis models described in Burn et al. (2021). The cases of host stars with masses of 0.5, 0.3, and 0.1 M_⊙ are shown from the top to bottom panels, as representative of early-, mid-, and late-type M dwarfs. Planets in the CARMENES sample are illustrated as filled (this work) and empty (Trifonov et al. 2018, 2020b; Quirrenbach et al. 2022) symbols. They are represented on each panel in three host star mass bins as labelled.
