The Nature of Unseen Companions in Massive Single-Line Spectroscopic Binaries

Hugues Sana, Michael Abdul-Masih, Gareth Banyard +14

Massive stars are predominantly found in binaries and higher order multiples. While the period and eccentricity distributions of OB stars are now well established across different…

HR 6819 is a binary system with no black hole -- revisiting the source with infrared interferometry and optical integral field spectroscopy

A. J. Frost, J. Bodensteiner, Th. Rivinius +16

Two scenarios have been proposed to match the existing observational constraints of the object HR 6819. The system could consist of a close inner B-type giant plus a black hole (BH…

Resolving the dynamical mass tension of the massive binary 9 Sagittarii

M. Fabry, C. Hawcroft, A. J. Frost +4

Direct dynamical mass measurements of stars with masses above 30 M are rare. This is the result of the low yield of the upper initial mass function and the limited number…

Constraining the Overcontact Phase in Massive Binary Evolution I. Mixing in V382 Cyg, VFTS 352, and OGLE SMC-SC10 108086

Michael Abdul-Masih, Hugues Sana, Calum Hawcroft +10

As potential progenitors of several exotic phenomena including gravitational wave sources, magnetic stars, and Be stars, close massive binary systems probe a crucial area of the pa…

Characterization of the variability in the O+B eclipsing binary HD 165246

Cole Johnston, Nicolas Aimar, Michael Abdul-Masih +8

O-stars are known to experience a wide range of variability mechanisms originating at both their surface and their near-core regions. Characterization and understanding of this var…

Is HR 6819 a triple system containing a black hole? -- An alternative explanation

J. Bodensteiner, T. Shenar, L. Mahy +10

HR 6819 was recently proposed to be a triple system consisting of an inner B-type giant + black hole binary with an orbital period of 40d and an outer Be tertiary. This interpretat…
