Thermal-timescale accretion does not always yield critical rotation in mass gainers
Chen Wang, Mike Y. M. Lau, Xiang-Dong Li +7
Binary evolution plays a central role in producing rapidly rotating stars. Previous studies have shown that mass gainers in binaries can reach critical rotation after accreting onl…
Stable mass transfer in massive binaries leading to merging black holes
Xiao-Tian Xu, Norbert Langer, Jakub Klencki +2
The vast majority of massive binary systems in the universe is evidently unsuited to produce merging binary black holes. However, several narrow evolutionary paths of isolated mass…
A comprehensive grid of massive binary evolution models for the Galaxy - Surface properties of post-mass transfer stars
Harim Jin, Norbert Langer, Andrea Ercolino +1
Massive stars often evolve in binary systems, in which binary interactions significantly affect their evolution. Massive stars in the Galaxy serve as valuable testbeds for this due…
A fundamental limit to how close binary systems can get via stable mass transfer shapes the properties of binary black hole mergers
Jakub Klencki, Philipp Podsiadlowski, Norbert Langer +4
Mass transfer in binary systems is the key process in the formation of various classes of objects, including merging binary black holes (BBHs) and neutron stars. Orbital evolution…
Evidence of polar and ultralow supernova kicks from the orbits of Be X-ray binaries
Ruggero Valli, Selma E. de Mink, Stephen Justham +7
Supernovae, the explosive deaths of massive stars, create heavy elements and form black holes and neutron stars. These compact objects often receive a velocity at formation, a "kic…
