Near-infrared characterization of evolved massive stars in M31 and M33
Michaela Kraus, Maria Laura Arias, Michalis Kourniotis +3
The upper region of the Hertzsprung-Russell diagram is populated by massive stars in a diversity of evolutionary stages, and the classification of these stars is often based on obs…
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…
HD 144812: A transition-phase massive star in a binary system
Michalis Kourniotis, Michaela Kraus, Maria Laura Arias +1
In this Letter, we shed light on the evolutionary phase of HD 144812, a Galactic yellow supergiant showing infrared excess that is typically expected for evolved stars undergoing e…
