Description
HD142527 observations were performed with SPHERE in the IRDIFS_EXT mode, with IRDIS observing in dual-band imaging with the K12 filter pair (wavelength K1=2.110 micron; K2=2.251 micron), while IFS obtains low-resolution (R=30) spectra between 0.95 and 1.65 micron. HD142527 was also observed in the SAM mode for SPHERE (we present the first observations that ever used the sparse aperture mask in SPHERE). We detect the accreting low-mass companion HD142527B at a separation of 73mas (11.4au) from the star.
