Mass ratio (planetary mass over stellar mass) plotted over the orbital period. The data are the same as in Fig. 8. The black dashed lines and magenta region show the boundaries of the sub-Jovian desert as in Fig. 8, but converted into the mass ratio assuming solar mass for the host star. Highlighted are NGTS-5b (blue, K-dwarf host), NGTS-1b (red, M-dwarf host), NGTS-2b (orange, F-dwarf host), NGTS-4b (green, K-dwarf host), and K2-60b (cyan, G-dwarf host). To highlight the influence of the stellar type, we also show for these stars the position in the diagram; the sun is also assumed to be a host star (i.e. stellar parameters are not taken into account; shaded). The arrows show the change that is effected when the host star is taken into account.
