Left panel: the mass column density of the dust grains is shown as a function of inclination angle θ. The column density of dust masses increases rapidly from the time of launch at ∼90° and reaches its peak around ∼80°. Following that, as the gas flows toward low inclinations (low θ, high z), the number density of dust declines and mass column density also likewise. This further confirms that new dust formation in these regions is negligible. Right panel: the optical depth τ(λ) of the medium, resulting from the dust formation, is presented as a function of the inclination angle θ, for four wavelengths, λ = 0.01, 0.1, 1, and 10 μm.
