Abundance analysis of stars hosting gas-rich debris disks
Sandipan P. D. Borthakur, Mihkel Kama, Luca Fossati +4
Accretion from protoplanetary or debris disks can contaminate the stellar photosphere, which is detectable in stars with radiative envelopes due to relatively slower photospheric m…
A rare phosphorus-rich star in an eclipsing binary from TESS
Colin P. Folsom, Mihkel Kama, Tõnis Eenmäe +6
Context: Few exoplanets around hot stars with radiative envelopes have been discovered, although new observations from the TESS mission are improving this. Stars with radiative env…
The yellow hypergiant - B[e] supergiant connection
Anna Aret, Michaela Kraus, Indrek Kolka +1
B[e] supergiants and yellow hypergiants share a number of common properties regarding their circumstellar environments. Using the forbidden [O I] and [Ca II] lines as disk tracers,…
Similarities in the structure of the circumstellar environments of B[e] supergiants and yellow hypergiants
Anna Aret, Indrek Kolka, Michaela Kraus +1
Yellow Hypergiants (YHGs) and B[e] supergiants (B[e]SGs), though in different phases in their evolution, display many features in common. This is partly due to the fact that both t…
B[e] Supergiants' circumstellar environment: disks or rings?
G. Maravelias, M. Kraus, A. Aret +3
B[e] Supergiants are a phase in the evolution of some massive stars for which we have observational evidence but no predictions by any stellar evolution model. The mass-loss during…
Inhomogeneous molecular ring around the B[e] supergiant LHA 120-S 73
M. Kraus, L. S. Cidale, M. L. Arias +8
We aim to improve our knowledge on the structure and dynamics of the circumstellar disk of the LMC B[e] supergiant LHA 120-S 73. High-resolution optical and near-IR spectroscopic d…
