| Abstract: |
In this contribution we review the properties of the post-red supergiant IRC+10420. Its A-type supergiant spectral classification, high wind outflow velocities, strong infrared excess combined with its abundances typical of massive evolved stars strongly indicate that IRC+10420 is a post-Red Supergiant. Indeed, the object can be classed as a genuine evolved “A[e]” supergiant, and as such may provide important clues to the understanding of the B[e] phenomenon. We give an update on the photometric evolution of the star and present new spectropolarimetric data. These imply that the Hα line forming region deviates from spherical symmetry. |
