Panchromatic imaging and spectroscopic observations of the mass ejections of RY Scuti

Abstract

We describe recent panchromatic imaging and spectroscopic studies of the supergiant, mass-transferring, binary star RY Scuti, which is in a brief transitional phase to become a Wolf-Rayet star and a stripped-envelope supernova.Comment: To appear in the proceedings of "Physics of Evolved Stars 2015 - A conference dedicated to the memory of Olivier Chesneau
