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…

The young massive SMC cluster NGC 330 seen by MUSE II. Multiplicity properties of the massive-star population

J. Bodensteiner, H. Sana, C. Wang +10

Observations of massive stars in young open clusters (< ~8 Myr) have shown that a majority of them are in binary systems, most of which will interact during their life. Populations…

Tango of celestial dancers: A sample of detached eclipsing binary systems containing g-mode pulsating components. A case study of KIC9850387

S. Sekaran, A. Tkachenko, M. Abdul-Masih +9

Eclipsing binary systems with components that pulsate in gravity modes ( modes) allow for simultaneous and independent constraints of the chemical mixing profiles of stars. We a…

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…

The 'hidden' companion in LB-1 unveiled by spectral disentangling

T. Shenar, J. Bodensteiner, M. Abdul-Masih +9

The intriguing binary LS V +22 25 (LB-1) has drawn much attention following claims of it being a single-lined spectroscopic binary with a 79-day orbit comprising a B-type star and…
