Mass–period diagram. The gray circles show the exoplanet data from exoplanet.eu, where the size of the circles is proportional to the planetary radius. The color map depicts the planet-detection rate as a percentage normalized to the sum of all known exoplanets in the mass range between 0.003 M_Jup and 20 M_Jup and orbital periods between 0.3 d and 200 d. The red dashed lines show the innermost limits of the sub-Jovian desert as defined by Mazeh et al. (2016). The orange star shows TOI-3568 b, which lies within the desert right in the transition between the two populations of the most frequent types of exoplanets, hot-Jupiters (top), and warm super-Earths (bottom).
