B fields in OB stars (BOB): Concluding the FORS2 observing campaign
M. Schoeller, S. Hubrig, L. Fossati +16
The "B fields in OB stars" (BOB) collaboration is based on an ESO Large Programme, to study the occurrence rate, properties, and ultimately the origin of magnetic fields in massive…
BONNSAI: correlated stellar observables in Bayesian methods
F. R. N. Schneider, N. Castro, L. Fossati +2
In an era of large spectroscopic surveys of stars and big data, sophisticated statistical methods become more and more important in order to infer fundamental stellar parameters su…
The Tarantula Massive Binary Monitoring project: II. A first SB2 orbital and spectroscopic analysis for the Wolf-Rayet binary R145
T. Shenar, N. D. Richardson, D. P. Sablowski +19
We present the first SB2 orbital solution and disentanglement of the massive Wolf-Rayet binary R145 (P = 159d) located in the Large Magellanic Cloud. The primary was claimed to hav…
A new prescription for the mass-loss rates of WC and WO stars
F. Tramper, H. Sana, A. de Koter
We present a new empirical prescription for the mass-loss rates of carbon and oxygen sequence Wolf-Rayet stars as a function of their luminosity, surface chemical composition, and…
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…
