Short-term variability and mass loss in Be stars V. Space photometry and ground-based spectroscopy of Cas
Camilla C. Borre, Dietrich Baade, Andrzej Pigulski +9
Context. Be stars are physically complex systems that continue to challenge theory to understand their rapid rotation, complex variability and decretion disks. Cassiopeiae (…
The study of unclassified B[e] stars and candidates in the Galaxy and Magellanic Clouds
C. A. H. Condori, M. Borges Fernandes, M. Kraus +2
We investigated 12 unclassified B[e] stars or candidates, 8 from the Galaxy, 2 from the Large Magellanic Cloud (LMC) and 2 from the Small Magellanic Cloud (SMC). Based on the analy…
Modelling the periodical variations in multiband polarisation and photometry for discs of binary Be stars
Despina Panoglou, Marcelo Borges Fernandes, Dietrich Baade +4
The tidal interaction of a Be star with a binary companion forms two spiral arms that cause orbital modulation of the Be disc structure. The aim of this work is to identify observa…
Short-term variability and mass loss in Be stars IV. Two groups of closely spaced, approximately equidistant frequencies in three decades of space photometry of Puppis (B7-8 IIIe)
D. Baade, A. Pigulski, Th. Rivinius +13
In early-type Be stars, groups of nonradial pulsation (NRP) modes with numerically related frequencies may be instrumental for the release of excess angular momentum through mass-e…
The Remarkable Be+sdOB Binary HD 55606 I: Orbital and Stellar Parameters
S. Drew Chojnowski, Jonathan Labadie-Bartz, Thomas Rivinius +20
Prompted by peculiar spectroscopic variability observed in SDSS/APOGEE -band spectra, we monitored the Be star HD 55606 using optical spectroscopy and found that it is an exotic…
BRITEning up the Be Phenomenon
D. Baade, Th. Rivinius, A. Pigulski +13
Observations of 25 Ori much expand the picture derived of other early-type Be stars with BRITE and SMEI. Two instead of one difference frequencies rule the variability: (a) The low…
