The Dusty Circumstellar Structure of the Yellow Hypergiant IRC +10420: Constraints from the SED and Near-Infrared Imaging Polarimetry

The yellow hypergiant IRC +10420 is a post-red supergiant evolving toward higher temperatures. We model its circumstellar dust with the radiative transfer code RADMC-3D, including polarized scattering, constrained by the spectral energy distribution (SED) from 0.4 $\mu$m to 1.3 mm and by the K'(2.2 $\mu$m) imaging pola...
