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…
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…
X-rays observations of a super-Chandrasekhar object reveal an ONeMg and a CO white dwarf merger product embedded in a putative SN Iax remnant
Lidia M. Oskinova, Vasilii V. Gvaramadze, Goetz Graefener +2
The merger of two white dwarfs (WD) is a natural outcome from the evolution of many binary stars. Recently, a WD merger product, IRAS 00500+6713, was identified. IRAS 00500+6713 co…
The Tarantula Massive Binary Monitoring: III. Atmosphere analysis of double-lined spectroscopic systems
L. Mahy, H. Sana, M. Abdul-Masih +17
Accurate stellar parameters of individual objects in binary systems are essential to constrain the effects of binarity on stellar evolution. These parameters serve as a prerequisit…
On the optically-thick winds of Wolf-Rayet stars
G. Gräfener, S. P. Owocki, L. Grassitelli +1
(abridged) The strong winds of Wolf-Rayet (WR) stars are important for the mechanical and chemical feedback of the most massive stars and determine whether they end their lives as…
The VLT-FLAMES Tarantula Survey XXIV. Stellar properties of the O-type giants and supergiants in 30 Doradus
O. H. Ramírez-Agudelo, H. Sana, A. de Koter +21
The Tarantula region in the Large Magellanic Cloud contains the richest population of spatially resolved massive O-type stars known so far. This unmatched sample offers an opportun…
