New paper on Magellanic Supergiants – Disk tracing for B[e] supergiants in the Magellanic Clouds

Disk tracing for B[e] supergiants in the Magellanic Clouds G. Maravelias, M. Kraus, A. Aret B[e] supergiants are evolved massive stars with a complex circumstellar environment. A number of important emission features probe the structure and the kinematics of the circumstellar material. In our survey of Magellanic Cloud B[e] supergiants …
