Candidate co-moving brown dwarf companion to Regulus (alf Leo) 3.9 pc away or 798,000 AUs. Regulus is a relatively old (≳1 Ga) quadruple system composed of the nearest B type star (alf Leo A, spT B8IV), a close-in pre-white dwarf about 0.35 AUs away (alf Leo Ab, spT DA or sdB?), a K dwarf at 5,000 AUs (alf Leo B, spT K2V) with an M dwarf about 60 AUs away (alf Leo C, spT M4V). If bound to the system as it appears, the brown dwarf should be labeled as “alf Leo D”, “alf Leo E” (if accounting the white dwarf as “alf Leo D”) or “alf Leo (ABC)b”.
