Disk tracing for B[e] supergiants in the Magellanic Clouds
arXiv:1507.08443 · doi:10.1051/eas/1571051
Abstract
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 we focus on the [OI] and [CaII] emission lines, which we identified in four more objects.
