Unveiling the evolutionary state of three B supergiant stars: PU Gem, CMa and CMa
Julieta P. Sánchez Arias, Péter Németh, Elisson S. G. de Almeida +3
We aim to combine asteroseismology, spectroscopy, and evolutionary models to establish a comprehensive picture of the evolution of Galactic blue supergiant stars (BSG). To start su…
BCD spectrophotometry for massive stars in transition phases
Y. J. Aidelman, M. Borges Fernandes, L. S. Cidale +7
Context. Stars in transition phases, like those showing the B[e] phenomenon and luminous blue variables (LBVs), undergo strong, often irregular mass ejection events. The prediction…
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…
Dense Molecular Environments of B[e] Supergiants and Yellow Hypergiants
Michaela Kraus, Michalis Kourniotis, Maria Laura Arias +2
Massive stars expel large amounts of mass during their late evolutionary phases. We aim to unveil the physical conditions within the warm molecular environments of B[e] supergiants…
Large-Scale Ejecta of Z CMa -- Proper Motion Study and New Features Discovered
Tiina Liimets, Michaela Kraus, Lydia Cidale +2
Z Canis Majoris is a fascinating early-type binary with a Herbig Be primary and a FU Orionis-type secondary. Both of the stars exhibit sub-arcsecond jet-like ejecta. In addition, t…
Revisiting the evolved hypergiants in the Magellanic Clouds
Michalis Kourniotis, Michaela Kraus, Olga Maryeva +2
The massive stars that survive the phase of red supergiants (RSGs) spend the rest of their life in extremity. Their unstable atmospheres facilitate the formation and episodic eject…
