Evolution of the accretion rate inferred from shock modeling of the core component, depending on the line. The accretion rate is computed as Ṁ=S n₀v₀μ. The right axis shows the corresponding L_acc = GṀM_p/Rp, with M_p = 13 M_Jup and R_p = 1.5 R_Jup. The accretion rates inferred from different lines are systematically ordered, which may point to a bias from deriving accretion rates from a single line.
