SPHERE contrast images of HD 167665 (see text). The white arrows indicate the position of HD 167665B. The central regions of the images are numerically masked out to hide bright stellar residuals. The white cross in each panel indicates the location of the primary star. The contrast scales are the same between the IRDIS images (top row) and between the IFS images (bottom row). The companion appears significantly fainter in the H3 image because the spectral filter matches methane absorption bands, hinting that the companion is a T-type sub-stellar object. The images were smoothed using a Gaussian filter with a 2 pixel width.
