When candidate protoplanet was inferred the companion star HD 142527 B had not yet been detected. Hence the candidate planet, if existing, is circumbinary along with the 140-500 AUs wide circumstellar disk.

An M dwarf companion star (spT M2 to M5-6, 0.1-0.4 M_Sol) is detected 14.71_-2.33^+8.18 AUs away and draws an eccentric orbit (e = 0.28_-0.1^+0.22, i = 126.27°_-2.13^+2.28).
