Spectral Effects of Pulsations in Blue Supergiants
Original language description
We have been spectroscopically monitoring a number of blue supergiants, focusing on several strategic photospheric and wind lines. Our aim is to detect line profile variability, and to determine its origin. Here, we present preliminary results for ρ Leo and ɛ Ori. We conduct an asteroseismic analysis of Hei λ6678. We find in each star multiple periods raging from hours to several days. In addition, we observe strong, night to night variability in Hα.
