Fig. 1

NACO imagery of YLW 16A in the Ks (Upper) and L (Lower) bands. The separation of the two sources in the L band is approximately 0.3″ (~40 AU projected separation). Both these images were obtained in the faint state (L band phase = 0.4656, K band phase = 0.6920). Color bars shown correspond to non-normalized counts. North is up and east is to the left.
