Planetary mass over orbital period. Plotted are all stars from the NASA Exoplanet Archive with a radius uncertainty lower than 10% or a mass uncertainty lower than 50%. The blue point shows NGTS-5b. Additionally, we highlight NGTS-1b in red (Bayliss et al. 2018), NGTS-2b in orange (Raynard et al. 2018), NGTS-4b in green (West et al. 2019), and K2-60b in cyan (Eigmüller et al. 2017). The black dashed lines show the boundaries of the sub-Jovian desert as determined in Mazeh et al. (2016). The magenta region shows the high-eccentricity migration boundary including tidal decay as presented in Owen & Lai (2018). The backgroundand the dotted black lines highlight the point density per grid element (the plot is divided into 40 × 40 equally spaced grid elements) of our sample. The yellow region on the left shows the sub-Jovian desert.
