Non-coronagraphic IRDIFS_EXT and SAM images of the HD 142527 system. Upper panel: images acquired on June 13, 2016. Left panel: PCA post-processing IFS image (averaged over all channels). The red cross marks the position of the central star. In this image the companion of HD 142527 is clearly visible. Right panel: central part of the PCA post-processing IRDIS image of HD 142527. Central panel: composition of the three RDI post-processing IFS images (from left to right: May 2015, March 2016, and June 2016). The orbital motion of B is clearly detected. Bottom panel: reconstructed images produced from the SAM data using the MiRA algorithm. The images show that we observe significant orbital motion for the companion HD 142527B between the SAM epochs, and that the point-source model used to calculate its position is a good approximation to the observed structure
