Central star is an eclipsing binary of W UMa type separated by 2.26 Solar radii (P = 0.30536973 d, m₁ = 0.58 M_Sol, m₂ = 1.09 M_Sol, r₁ = 0.75 R_Sol, r₂ = 1 R_Sol, T₁ = 6400 K and T₂ = 6200 K, L₁ = 0.91 L_Sol and L₂ = 1.33 L_Sol) and also forms a triple system with a late G dwarf companion 12.1 arcseconds away (1176 AUs at 98 pc). Hence accounting the proposted substellar companion detected through timing, the system turns out to be quadruple.
