An absence of binary companions to Wolf-Rayet stars in the Small Magellanic Cloud: implications for mass loss and black hole masses at low metallicity
A. Schootemeijer, T. Shenar, N. Langer +5
In order to predict the black hole mass distributions at high redshift, we need to understand whether very massive single stars ( M) at low metallicity lose their…
Modeling non-thermal emission from SN 1987A
Robert Brose, Jonathan Mackey, Sean Kelly +2
The remnant of SN 1987A is the best-studied object of its kind. The rich data-set of its thermal and non-thermal emission across the electromagnetic spectrum poses a unique testbed…
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…
The Tarantula Massive Binary Monitoring. IV. Double-lined photometric binaries
L. Mahy, L. A. Almeida, H. Sana +10
A high fraction of massive stars are found to be binaries but only a few of them are reported as photometrically variable. By studying the populations of SB2 in the 30 Doradus regi…
Properties of OB star-black hole systems derived from detailed binary evolution models
N. Langer, C. Schürmann, K. Stoll +38
The recent gravitational wave measurements have demonstrated the existence of stellar mass black hole binaries. It is essential for our understanding of massive star evolution to i…
Constraining mixing in massive stars in the Small Magellanic Cloud
Abel Schootemeijer, Norbert Langer, Nathan J. Grin +1
Context. The evolution of massive stars is strongly influenced by internal mixing processes such as semiconvection, convective core overshooting, and rotationally induced mixing. N…
Subsonic structure and optically thick winds from Wolf--Rayet stars
Luca Grassitelli, Norbert Langer, Nathan J. Grin +3
Wolf-Rayet star's winds can be so dense and so optically thick that the photosphere appears in the highly supersonic part of the outflow, veiling the underlying subsonic part of th…
The VLT-FLAMES Tarantula Survey XXVI: Properties of the O-dwarf population in 30 Doradus
C. Sabín-Sanjulián, S. Simón-Díaz, A. Herrero +21
The VLT-FLAMES Tarantula Survey has observed hundreds of O-type stars in the 30 Doradus region of the Large Magellanic Cloud (LMC). We study the properties of 105 apparently single…
The Tarantula Massive Binary Monitoring: I. Observational campaign and OB-type spectroscopic binaries
L. A. Almeida, H. Sana, W. Taylor +24
Massive binaries (MBs) play a crucial role in the Universe. Knowing the distributions of their orbital parameters (OPs) is important for a wide range of topics, from stellar feedba…
The VLT-FLAMES Tarantula Survey XXV. Surface nitrogen abundances of O-type giants and supergiants
N. J. Grin, O. H. Ramirez-Agudelo, A. de Koter +19
Theoretically, rotation-induced chemical mixing in massive stars has far reaching evolutionary consequences, affecting the sequence of morphological phases, lifetimes, nucleosynthe…
