Scattered light images of HV Tau. The left most panel shows the F814W image obtained by Stapelfeldt et al. (2003) while the other three panels show our new images obtained at H and K _s with VLT/NACO (the K _s image is the coronagraphic one), and at L′ with Keck/NIRC2 and the LGS adaptive optics system. The F814W image is shown on the logarithmic stretch to better highlight low-level features. The arrows point to the "rays" identified by Stapelfeldt et al. (2003). All other images are shown on a square root stretch. In all cases, the field of view is 6'' across. As discussed in the text, the L′ image has been smoothed and resampled to improve the signal-to-noise ratio without degrading its spatial resolution.
