The B-type Binaries Characterisation Programme II. VFTS 291: A stripped star from a recent mass transfer phase
J. I. Villaseñor, D. J. Lennon, A. Picco +12
Recent studies of massive binaries with putative black hole companions have uncovered a phase of binary evolution that has not been observed before, featuring a bloated stripped st…
Properties of the Be-type stars in 30 Doradus
P. L. Dufton, D. J. Lennon, J. I. Villasenor +5
The evolutionary status of Be-type stars remains unclear, with both single-star and binary pathways having been proposed. Here, VFTS spectroscopy of 73 Be-type stars, in the spectr…
The VLT-FLAMES survey of massive stars. NGC2004#115: A triple system hosting a possible short period B+BH binary
D. J. Lennon, P. L. Dufton, J. I. Villaseñor +5
The star NGC2004#115 in the LMC, originally classified as an (SB1) Be spectroscopic binary, bears some morphological resemblance to the Galactic systems LB-1 and HR 6819, both of w…
The B-type Binaries Characterisation Programme I. Orbital solutions for the 30 Doradus population
J. I. Villaseñor, W. D. Taylor, C. J. Evans +6
We present results from the B-type Binaries Characterisation (BBC) programme, a multi-epoch spectroscopic study of 88 early B-type binary candidates in the 30 Doradus region of the…
The NGC 346 massive star census: Nitrogen abundances for apparently single, narrow lined, hydrogen core burning B-type stars
P. L. Dufton, C. J. Evans, D. J. Lennon +1
Analyses of large spectroscopic surveys of early-type stars in the LMC have found an excess of nitrogen enriched B-type targets with a vsini<40 km/s compared with the predictions o…
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…
