Description
From a theoretical point-of-view, magnetic fields are crucial to the evolution of planet-forming disks. However, profound observational constraints are pending. Presently, the number of cutting-edge polarization observations presenting inconclusive data increases continuously. In very recent years, polarization at mm-wavelengths, the classical tracer of magnetic fields, emerged as highly ambiguous, and the pressing demand for comprehensive tools to analyze these new observations is growing.
I will present an overview on the sources of continuum polarization with focus on the impact of grain alignment, scattering, and grain porosity on the polarization measurement – as well as a potential solution to this dusty ambiguousness, linearly polarized gas emission.
