Discovery images of HD 133778B. The left and right panels show data from 2016 May 16 and 2017 June 22 respectively. In each case, the SPHERE/IRDIS data are reduced using a principal component analysis algorithm to remove stellar speckles, and the H2 and H3 data are coadded. The host star is in the center behind the coronagraphic mask, and the companion is clearly visible to the left-hand side of the image. Note that the bright circular ring at ∼0.″9 is the ring of speckle noise at the edge of the adaptive optics control radius, smeared due to the rotation between images, and is not related to the debris disk in this system.
