A new observational tracer for high-density disc-like structures around B[e] supergiants
Original language description
Based on the high-resolution optical spectra of a sample of B[e] supergiants in the Magellanic Clouds we especially searched for tracers of the kinematics within their discs. Besides the well-known [O i] lines, we discovered the [Ca ii] 7291, 7324 lineswhich can be used as a complementary set of disc tracers. We find that these lines originate from very high density regions, located closer to the star than the [O i] 5577 line-forming region.
