HOney-BeeS II. Be-X-ray binaries as testbeds for spectroscopic studies of Be stars
S. Janssens, H. Sana, T. Shenar +2
The majority of massive classical Be stars are thought to be binary interactions products. Their rapid rotation and often strong, variable, and emission-line dominated spectrum, ma…
The lack of fast rotators in Cyg OB2. I. Insights from spectral reclassification of its B0 population
D. Galán-Diéguez, S. R. Berlanas, A. Herrero +4
Context. Cygnus OB2, in the Cygnus X complex -- one of the most active star-forming regions of the Galaxy -- hosts hundreds of O- and B-type stars at different evolutionary stages.…
The Triple System V1371 Tau: An Eclipsing Binary with an Outer Be Star
Danilo F. Rocha, Marcelo Emilio, Jonathan Labadie-Bartz +10
Although triple systems are common, their orbital dynamics and stellar evolution remain poorly understood. We investigated the V1371 Tau system using TESS photometry, multi-epoch s…
A high fraction of close massive binary stars at low metallicity
H. Sana, T. Shenar, J. Bodensteiner +74
At high metallicity, a majority of massive stars have at least one close stellar companion. The evolution of such binaries is subject to strong interaction processes, heavily impac…
Large-scale variability in macroturbulence driven by pulsations in the rapidly rotating massive star Zeta Oph from high-cadence ESPRESSO spectroscopy and TESS photometry
A. J. Kalita, D. M. Bowman, M. Abdul-Masih +1
Despite their importance, the dynamical properties of massive stars remain poorly understood. Rotation is a key driver of internal mixing and angular momentum transport, significan…
Physics Of Eclipsing Binaries. IX. Spectroscopic module
Miroslav Brož, Andrej Prša, Kyle E. Conroy +1
Spectroscopic observations constrain the fundamental properties of stellar atmospheres, in particular, the effective temperature, the gravitational acceleration, or the metallicity…
Binarity at Low Metallicity (BLOeM) -- Multiplicity properties of Oe and Be stars
J. Bodensteiner, T. Shenar, H. Sana +40
Rapidly rotating classical OBe stars have been proposed as the products of binary interactions, and the fraction of Be stars with compact companions implies that at least some are.…
Newborn Be star systems observed shortly after mass transfer
Th. Rivinius, R. Klement, S. D. Chojnowski +24
Many classical Be stars acquire their very rapid rotation by mass and angular-momentum transfer in massive binaries. Short-lived intermediate-phase objects have only been discovere…
