We detect several bright blobs at ˜180 mas separation from the star, and a faint arc-like structure in the IFS data. Our reference differential imaging (RDI) data analysis also finds a bright ring at the same separation. We show, using a simulation based on polarized light data, that these blobs are actually part of the ring at 180 mas. These results demonstrate that the earlier detections of blobs in the H and K<SUB>S</SUB> bands at these separations in Biller et al. as potential planet/substellar companions are actually tracing a bright ring with a Keplerian motion. Moreover, we detect in the images an additional bright structure at ˜93 mas separation and position angle of 355°, at a location very close to previous detections. It appears point-like in the YJ and K bands but is more extended in the H band. We also marginally detect an inner ring in the RDI data at ˜100 mas. Follow-up observations are necessary to confirm the detection and the nature of this source and structure.STAMPAenArticle10.1093/mnras/stx23182-s2.0-85038909013http://arxiv.org/abs/1709.01734v2https://academic.oup.com/mnras/article/473/2/1774/45879112018MNRAS.473.1774LFIS/05 - ASTRONOMIA E ASTROFISICAERC sectors::Physical Sciences and Engineering
