TOI-519 b in the context of currently known transiting planet and brown dwarf systems. First (top), we show the radius as a function of the orbital period for transiting planets and brown dwarfs (BDs) with a focus on companions around cool (T_eff <4000 K) host stars. Transiting planets around cool hosts are shown as orange-rimmed stars, transiting BDs around cool hosts as orange-rimmed circles, transiting BDs around hot hosts (T_eff >4000 K) as dark-blue-rimmed circles, and transiting planets around hot hosts as blue-shaded areas. Next (bottom), we show the radius as a function of the effective temperature of the host star for transiting planets (stars) and brown dwarfs (circles). Objects with P < 1 d are coloured in dark blue, 1 < P < 5 d in orange, and P > 5 d in light grey.
