Interplay between pulsations and mass loss in the blue supergiant 55 Cygnus = HD 198478
M. Kraus, M. Haucke, L. S. Cidale +14
Blue supergiant stars are known to display photometric and spectroscopic variability that is suggested to be linked to stellar pulsations. Pulsational activity in massive stars str…
Pulsations as a mass-loss trigger in evolved hot stars
Michaela Kraus, Dieter H. Nickeler, Maximiliano Haucke +5
During the post-main sequence evolution massive stars pass through several short-lived phases, in which they experience enhanced mass loss in the form of clumped winds and mass eje…
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…
Detection of a 1.59 h period in the B supergiant star HD 202850
Michaela Kraus, Sanja Tomic, Mary E. Oksala +1
Photospheric lines of B-type supergiants show variability in their profile shapes. In addition, their widths are much wider than can be accounted for purely by stellar rotation. Th…
Investigation of Residual Blaze Functions in Slit-Based Echelle Spectrograph
Petr Škoda, Brankica Šurlan, Sanja Tomić
We have studied the Residual Blaze Functions (RBF) resulting from division of individual echelle orders by extracted flat-field in spectra obtained by slit-fed OES spectrograph of…
