Type Ib supernovae are bluer than Type Ic supernovae
Harim Jin, Selma E. de Mink, Sebastian Holzner +5
The study finds that Type Ib supernovae are systematically bluer at peak than Type Ic supernovae, suggesting intrinsic differences in progenitor stripping rather than host galaxy r…
Neutron star-companion interaction in core collapse supernovae. Population synthesis based on detailed binary evolution models
Andrea Ercolino, Norbert Langer, Avishay Gal-Yam +6
Most massive stars live in binary systems. When the first supernova (SN) in a binary occurs, the ejecta hit the companion, which may inflate as a consequence, and then interacts wi…
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…
Binary mass transfer in 3D: Mass Transfer Rate and Morphology
T. Ryu, R. Sari, S. E. de Mink +6
Mass transfer is crucial in binary evolution, yet its theoretical treatment has long relied on analytic models whose key assumptions remain debated. We present a direct and systema…
Populations of evolved massive binary stars in the Small Magellanic Cloud I: Predictions from detailed evolution models
X. -T. Xu, C. Schürmann, N. Langer +13
Context. The majority of massive stars are born with a close binary companion. How this affects their evolution and fate is still largely uncertain, especially at low metallicity.…
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…
