Caption: Figure 5.
LkHα 225 South low-dispersion optical spectrum from Palomar/DBSP (magenta) and infrared spectrum from IRTF/SpeX (red). LkHα 225 South appears significantly reddened, even in outburst. Figures 6 and 9, respectively, offer expanded views of the optical and infrared portions of the spectra. Inset illustrates the strong Na ID and Hα features; both have blueshifted absorption components when examined in higher spectral dispersion data (see Figure 11).
