Discovery of the first B[e] supergiants in M 31
Michaela Kraus, Lydia S. Cidale, Maria Laura Arias +2
B[e] supergiants (B[e]SGs) are transitional objects in the post-main sequence evolution of massive stars. The small number of B[e]SGs known so far in the Galaxy and the Magellanic…
Pulsations in the Late-type B Supergiant Star HD 202850
Sanja Tomic, Michaela Kraus, Mary Oksala
HD 202850 is a late B-type supergiant. It is known that photospheric lines of such stars vary. Due to macroturbulence the lines are much wider than expected. Macroturbulence has be…
Probing the ejecta of evolved massive stars in transition: A VLT/SINFONI K-band survey
M. E. Oksala, M. Kraus, L. S. Cidale +2
Massive evolved stars in transition phases, such as Luminous Blue Variables (LBVs), B[e] Supergiants (B[e]SGs), and Yellow Hypergiants (YHGs), are not well understood, and yet cruc…
