Gravity modes and potential evidence for Rossby Waves in late O-type supergiants
Lydia S. Cidale, Alejandra Christen, Aldana Alberici Adam +6
The properties of O-type supergiant stars remain largely unexplored. By analysing their light variations, we can unravel underlying physical phenomena, such as binarity, stellar pu…

Variability of Galactic blue supergiants observed with TESS
Michalis Kourniotis, Lydia S. Cidale, Michaela Kraus +2
Blue supergiants (BSGs) mediate between the main sequence and the late stages of massive stars, which makes them valuable for assessing the physics that drives the stars across the…
