Left panel: same as right panel in Fig. 3 but for solar analogs containing 62 “single” stars (red open circles) and 33 stars hosting planets (blue filled circles), with the most massive planet in an orbital period Porb < 25 days (6 stars, yellow filled triangles), 100 < Porb < 600 days (14 stars, violet filled squares), 900 < Porb < 4250 days (13 stars, green filled triangles). The mean abundance differences, Δ [X/H] SUN − STARS, and linear fits have been artificially shifted by − 0.15 dex, for the sake of clarity. Horizontal dashed-dot lines show the zero point levels for each set of points. Right panel: same as left panel but for planet-host stars with the minimum mass of the least massive planet in the ranges: mpsini < 14 M⊕ (8 stars, yellow filled triangles), 14 < mpsini < 30 M⊕ (4 stars, violet filled squares), mpsini > 30 M⊕ (21 stars, green filled triangles).
