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…
New Insight into the FS CMa System MWC 645 from Near-Infrared and Optical Spectroscopy
Andrea F. Torres, María L. Arias, Michaela Kraus +2
The B[e] phenomenon is manifested by a heterogeneous group of stars surrounded by gaseous and dusty circumstellar envelopes with similar physical conditions. Among these stars, the…
A new outburst of the yellow hypergiant star Rho Cas
Michaela Kraus, Indrek Kolka, Anna Aret +5
Yellow hypergiants are evolved massive stars that were suggested to be in post-red supergiant stage. Post-red supergiants that evolve back to the blue, hot side of the Hertzsprung-…
