Chemical fingerprints of binary mass transfer in massive stars
Harim Jin, Norbert Langer
The majority of massive stars are born in close binary systems. As stars expand when they age, mass transfer or even a merger with their companion is inevitable. However, most bina…
Multiplicity of Massive Stars at Low Metallicity: Early Results from the BLOeM Campaign
T. Shenar, J. Bodensteiner, M. Abdul-Masih +73
The BLOeM campaign presents the first large‑scale spectroscopic survey of 929 massive stars in the Small Magellanic Cloud, revealing a high intrinsic binary fraction (>70%) among m…
Binary-induced mass increase and helium enrichment of the envelopes of Type~IIP supernova progenitors
Caroline Mannes, Norbert Langer, Andrea Ercolino
Binary interactions are expected to play a major role in shaping the progenitor population of core-collapse supernovae, particularly in the era of deep, high-cadence transient surv…
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…
The demographics of core-collapse supernovae. The role of binary evolution and CSM interaction
Andrea Ercolino, Harim Jin, Norbert Langer +3
The observational properties of core-collapse supernovae (CC-SNe) are shaped by the envelopes of their progenitors. In massive binary systems, mass-transfer alters the pre-SN struc…
A new sample of massive B-type contact binary candidates from the OGLE survey of the Magellanic Clouds
Athira Menon, Michal Pawlak, Daniel J. Lennon +2
Massive contact binaries (CBs) are key to understanding close-binary evolution and stellar mergers, yet their study has been limited by the scarcity of observed systems, particular…
