A stripped helium star in the potential black hole binary LB-1
Andreas Irrgang, Stephan Geier, Simon Kreuzer +2
The recently claimed discovery of a massive () black hole in the Galactic solar neighborhood has led to controversial discussions because it…
The EREBOS project -- Investigating the effect of substellar and low-mass stellar companions on late stellar evolution
V. Schaffenroth, B. N. Barlow, S. Geier +14
Eclipsing post-common envelope binaries are highly important for resolving the poorly understood, very short-lived common envelope phase. Most hot subdwarfs (sdO/Bs) are the bare H…
Hypervelocity stars in the Gaia era: Runaway B stars beyond the velocity limit of classical ejection mechanisms
Andreas Irrgang, Simon Kreuzer, Ulrich Heber
Young massive stars in the halo are assumed to be runaway stars from the Galactic disk. Possible ejection scenarios are binary supernova ejections (BSE) or dynamical ejections from…
A quantitative spectral analysis of 14 hypervelocity stars from the MMT survey
Andreas Irrgang, Simon Kreuzer, Ulrich Heber +1
Hypervelocity stars (HVSs) travel so fast that they may leave the Galaxy. The tidal disruption of a binary system by the supermassive black hole in the Galactic center is widely as…
Efimov physics in a finite volume
Simon Kreuzer, H. -W. Hammer
Three bosons with large scattering length show universal properties that do not depend on the details of the interaction at short distances. In the three-boson system, these proper…
