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…
Two waves of massive stars running away from the young cluster R136
Mitchel Stoop, Alex de Koter, Lex Kaper +10
Massive stars are predominantly born in stellar associations or clusters. Their radiation fields, stellar winds, and supernovae strongly impact their local environment. In the firs…
The VLT-FLAMES Tarantula Survey: Observational evidence for two distinct populations of massive runaway stars in 30 Doradus
H. Sana, O. H. Ramírez-Agudelo, V. Hénault-Brunet +17
Two main scenarios have been proposed for origin of massive runaway stars -- dynamical ejection or release from a binary at the first core collapse -- but their relative contributi…
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…
The Tarantula Massive Binary Monitoring V. R 144: a wind-eclipsing binary with a total mass > 140 Msun
T. Shenar, H. Sana, P. Marchant +21
R 144 is the visually brightest WR star in the Large Magellanic Cloud (LMC). R 144 was reported to be a binary, making it potentially the most massive binary thus observed. We perf…
A relation between the radial velocity dispersion of young clusters and their age: Evidence for hardening as the formation scenario of massive close binaries
M. C. Ramírez-Tannus, F. Backs, A. de Koter +8
The majority of massive stars ( ) in OB associations are found in close binary systems. Nonetheless, the formation mechanism of these close massive binaries is…
