Left panel: amount of stellar flux received as a function of planetary radius for the sample of known exoplanets (black dots). F⊕ is the Earth’s incident irradiation from the Sun. The large blue dots show the position of Earth and Jupiter. The black and green labels denote the location where exoplanets are common (Jupiter, sub-Neptune, and rocky planets) and scarce (Neptune desert; radius valley, right panel), respectively. Right panel: radius valley distribution for planets in short-period orbits (Fulton et al. 2017). The structure in this distribution is believed to be the outcome of a combination of planet formation and planet evolution processes. -- astro-ph.IM
