Abstract: We present potential detections of H-band scattered light emission aroundfour young star, selected from a total sample of 45 young stars observed withthe CIAO coronagraph of the Subaru telescope. Two CTTS, CI Tau and DI Cep, andtwo WTTS, LkCa 14 and RXJ 0338.3+1020 were detected. In all four cases, theextended emission is within the area of the residual PSF halo, and is revealedonly through careful data reduction. We compare the observed extended emissionwith simulations of the scattered light emission, to evaluate the plausibilityand nature of the detected emission.
