Mass vs orbital period diagram for planets with mass measurements. Shown are planets found by the transit method (light cyan circles), planets found by radial velocity measurements (blue triangles), and planets found by other methods (gray squares). The filled black symbols represent planets orbiting around M stars (i.e., stars with T_eff in the range2500–4000 K), each symbol representing the discovery method as explained before. The black dashed lines represent the limits of the Neptunian desert defined by Mazeh et al. (2016). The position of TOI-674b in this diagram is shown by the red star.
