A temporal, synthetic evolution of the luminosity of Brγ line for the bow shock contribution, the accretion contribution, and the total light curve. The wind parameters of the star were set to ṁ_w = 5 × 10^-9M_⊙ yr^-1 and v_w = 10 km s^-1 (logarithms of these values are in the parentheses). The shaded region corresponds to the constant, observationally inferred luminosity of Brγ line (Valencia-S. et al. 2015).
