Perrier et al. (2003) reported HD 13507 b as a massive brown dwarf (m sin i = 52 Jupiter masses) with orbital period of 3000 days (e = 0.14). Wilson et al. (2006) refined the mass as 67 Jupiter masses but the latest orbital solution by Grandjean et al. (2021) does not confirm a single object, rather implies two substellar companions in eccentric resonant orbits.
