The Single Star Path to Be Stars
Ben Hastings, Chen Wang, Norbert Langer
Be stars are rapidly rotating B main sequence stars, which show line emission due to an outflowing disc. By studying the evolution of rotating single star models, we can assess the…
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…
A Sparkler in the Fireworks Galaxy: Discovery of an Ultraluminous X-ray Transient with a Strong Oxygen Line in NGC 6946
Chen Wang, Roberto Soria, Junfeng Wang
We discovered and studied an ultraluminous X-ray source (CXOU J203451.1+601043) that appeared in the spiral galaxy NGC 6946 at some point between 2008 February and 2012 May, and ha…
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…
