Period–radius (top) and period–mass (bottom) diagrams of all the extrasolar planets and brown dwarfs that have been confirmed to date via transits or RVs². The blue shaded scale indicates the density of known planets. All planets and brown dwarfs around host stars with T_eff < 4000 K are individually marked with a red star or a red circle, respectively. Transiting brown dwarfs around other stellar types are marked with black circles. The position of TOI-263 b is marked with a larger red star, together with the radius and mass measurement uncertainties (within the symbol size in the latter case). For comparison, we also show the transiting brown dwarf NGTS-7Ab, which is marked separately, some individual planets, marked with Latin numbers – Kepler-45 (0), NGTS-1 (1), HATS-6 (2), and HATS-71A (3) – and known brown dwarfs, marked with Roman numerals – LP 261-75b (I), AD 3116 b (II), NLTT 41 135 b (III), and RIK 72 b (IV).
