Giant planet detections as a function of stellar mass. From the HARPS and CARMENES planets presented here (red), the California Legacy Survey (Rosenthal et al. 2021, gray), and our synthetic NGM planets (blue), we include detections with RV semi-amplitude K > 10 m s⁻¹, M sin(i) > 100 M_⊙, and P < 1000 d. We removed planets around close spectroscopic binaries (P < 20 yr) reported in Rosenthal et al. (2021). In addition, we show the fit of Ghezzi et al. (2018) for metallicities consistent with the assumptions made to draw the synthetic planets. Shaded areas and vertical lines denote 68% confidence intervals, respectively. We note that the HARPS &CARM₇₀ sample is limited to M dwarfs ≲0.7 M_⊙. The observed giant planets around very low-mass stars indicate a possible break of the monotonie stellar mass trend at around ~0.5 M_⊙, which theoretical predictions fail to reproduce. If type-I migration is inhibited by a factor ×10 in the simulations (dashed blue line), giant planets occur also in systems with lower stellar masses.
