Post-processed science frames from IRDIS (left) and IFS (right) instruments. Angular and spectral differential imaging was applied with one principal component used for modelling and subtraction of the residual stellar light (see Sect. 3). The IRDIS image combines the two wavelengths channels K1 and K2. Dark circles on the images show the -diameter size of the coronagraph. The blue circles indicate the previously resolved companions Ab and E. White circles indicate the IRDIS sources detected at the 5σ level while yellow circles indicate the new companion QZ Car Ad. The IFS image is ; the IRDIS is 12″ × 12″.
