The motivation was to test the models of magneto-centrifugal launch of jets via the determination of the magnetic configuration at the disk surface. The analysis of these data, however, reveals that self-scattering of dust thermal radiation dominates the polarization pattern. It is shown that even if no information on the magnetic field can be derived in this case, the polarization data are a powerful tool for the diagnostics of the properties and the evolution of dust in protoplanetary disks.||Funding Details:||European Commission - Seventh Framework Programme (FP7)||Type of material:||Conference Publication||Publisher:||Springer||Series/Report no.:||Astrophysics and Space Science Proceedings book series (ASSSP, volume 55)||Copyright (published version):||2019 Springer||Keywords:||Jets; Outflows; Polarization; Dust properties; DG Tau; CW Tau||DOI:||10.1007/978-3-030-14128-8_13||Language:||en||Status of Item:||Peer reviewed||Is part of:||Saulty, C.
