Introducing the ASSESS project: Episodic Mass Loss in Evolved Massive Stars -- Key to Understanding the Explosive Early Universe
A. Z. Bonanos, G. Maravelias, M. Yang +6
Episodic mass loss is not understood theoretically, neither accounted for in state-of-the-art models of stellar evolution, which has far-reaching consequences for many areas of ast…
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,…
A new outburst of the yellow hypergiant star Cas
Anna Aret, Michaela Kraus, Indrek Kolka +1
Spectroscopic monitoring of the yellow hypergiant Cas revealed a new outburst in 2013, which is obvious from the development of TiO bands in the spectra. Also many atmospheric…
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…
Clumpy molecular structures revolving the B[e] supergiant MWC 137
M. Kraus, L. S. Cidale, T. Liimets +10
The peculiar emission-line star MWC 137 with its extended optical nebula was recently classified as B[e] supergiant. To study the spatial distribution of its circumstellar molecula…
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…
