Painting a Family Portrait of the Yellow Super- and Hypergiants in the Milky Way I. Constraining the Distances and Luminosities
A. Kasikov, A. Mehner, I. Kolka +1
Context. Distances to evolved massive stars in the Milky Way are not well constrained by Gaia parallaxes due to their brightness and variability. This makes it difficult to determi…

Photometric and spectroscopic variability of the blue supergiant rho Leo
V. A. Checha, A. Aret, I. Kolka +12
Context. The post-main-sequence evolution of massive stars remains poorly understood, particularly for blue supergiants. These objects play a crucial role in the dynamical and chem…

Atmospheric dynamics of the hypergiant RW Cep during the Great Dimming
A. Kasikov, I. Kolka, A. Aret +5
The hypergiant RW Cep is one of the largest stars in our galaxy. The evolution and mass loss of such stars has profound effects on their surrounding regions and the galaxy as a who…
