Planet distribution in the (P, M_P) diagram. In the top-left panel only the planets around evolved stars with log g ≤ 4 dex are shown. In the bottom-left panel we plot only the planets detected with the transiting method, and in the right panel we present the planets orbiting FGK dwarfs (log g > 4 dex). The dotted line represents the approximate (empirical) detection limit for planets, and the dashed line is the linear fit for the full sample.
