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…
Simultaneous J-, H-, K- and L-band spectroscopic observations of galactic Be stars. I. IR atlas
Y. R. Cochetti, M. L. Arias, L. S. Cidale +2
It is already accepted that Be stars are surrounded by circumstellar envelopes, which are mostly compatible with a disc geometry in Keplerian rotation. We aim to obtain a more comp…
Intriguing detection of CO molecular emission in a classical Be star
Y. R. Cochetti, M. L. Arias, M. Kraus +4
In the group of B stars with spectroscopic peculiarities, we can find the Be and the B[e] stars. The Be stars are early-type rapid rotators that present, as their principal charact…
Near-infrared characterization of four massive stars in transition phases
Yanina R. Cochetti, Michaela Kraus, María L. Arias +5
Massive stars typically undergo short-lived post-main sequence evolutionary phases with strong mass loss and occasional mass eruptions. Many of such massive stars in transition pha…
