Portions of the 2019 August Keck/HIRES spectrum illustrating the strong wind of LkHα 225 South via blueshifted absorption features. In the lower-right panel, the narrower Ca I absorption line validates the wavelength scale and thus our heliocentric correction to the stellar rest velocity. The Hα profile (upper-right panel) has a clear P Cygni nature, with the absorption against the emission profile extending to about −210 km s⁻¹ on the blue side, though the emission wing continues to about −325 km s⁻¹. The red-side emission peaks at +85 km s⁻¹ and extends to +275 km s⁻¹. Broad blueshifted absorption is also seen in Li I (lower-right panel), and the K I doublet, the O I triplet, the Na I D doublet lines, the Mg I b triplet lines, and among the wind-sensitive Fe II lines. The typical terminal velocity in the metal lines is −150 km s⁻¹.
