Polarimetry as a Probe of Protoplanetary Disk Properties

Learn about protoplanetary disk properties through polarimetry in this 49-minute astronomy lecture that explores how planet formation begins during a planetary system's early stages. Discover how polarization observations provide crucial insights into dust properties within protoplanetary disks, with detailed explanations of observational studies and models of polarized emission at millimeter and sub-millimeter wavelengths. Explore how thermal emission scattering by dust creates polarized emission patterns matching disk observations, and understand how multi-wavelength polarized emission analysis reveals information about dust grain sizes and distributions. Examine topics including disk evolution, signatures of planet formation, dust growth mechanisms, unexpected findings from HL Tau observations, scattering in inclined disks, and the role of porous aggregates. Gain insights into cutting-edge research through preliminary results from HD 97048 and learn about future directions in disk polarization studies.
