Wallace & Casey (2026): alternative solution considers two companions, either a pair of substellar objects (m₁ = 30 M_Jup with P₁ = 3 y and a planet with P₂ ≥ 1 y) or a very low-mass star (m₁ = 0.09 M_Sol with P₁ = 0.5 y) plus a likely circumbinary brown dwarf. Additional solutions are possible as well.
