Spectral energy distributions (SEDs) of the Pop III star tidal flares in the rest frame of the host galaxy. The default parameter set used for plotting this figure and the those subsequent is M _BH = 10⁶ M _⊙, M _⋆ = 300M _⊙ (M ₃₀₀), Z = 10⁻⁵(Z ₋₅), f _out = 0.5, f _v = 1, and β = β _c = 1.85 (the red solid curve) unless specified otherwise. (a) The evolution of the SEDs at different epochs: t _edge/2, t _edge (peak luminosity), 2× t _edge, and 4× t _edge. (b) The SEDs at t = t _edge for various Pop III stars of different masses or metallicities and a solar-type star. (c) The dependence of the SEDs (at t = t _edge) on M _BH. (d) The dependence of the SEDs (at t = t _edge) on other parameters including the mass outflow fraction (f _out), the ratio between wind velocity and escape velocity (f _v ), and the stellar orbital penetration parameter β (with β _c = 1.85 being the critical value for full tidal disruption).
