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…
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 interact wit…
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…
Mass-transferring binary stars as progenitors of interacting hydrogen-free supernovae
Andrea Ercolino, Harim Jin, Norbert Langer +1
Stripped-envelope supernovae (SNe) are H-poor transients produced at the end of the life of massive stars that previously lost their H-rich envelope. Their progenitors are thought…
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…
Boron depletion in Galactic early B-type stars reveals two different main sequence star populations
Harim Jin, Norbert Langer, Daniel J. Lennon +1
The evolution and fate of massive stars are thought to be affected by rotationally induced internal mixing. The surface boron abundance is a sensitive tracer of this in early B-typ…
A sequence of Type Ib, IIb, II-L, and II-P supernovae from binary-star progenitors of varying initial separation
Luc Dessart, Claudia P. Gutierrez, Andrea Ercolino +2
Over the last decade, evidence has accumulated that massive stars do not typically evolve in isolation but instead follow a tumultuous journey with a companion star on their way to…
Boron Abundances in Early B Dwarfs of the Galactic Open Cluster NGC 3293
Charles R. Proffitt, Harim Jin, Simone Daflon +4
New boron abundances or upper limits have been determined for 8 early-B stars in the young Galactic open cluster NGC 3293, using ultraviolet spectra obtained by the Hubble Space Te…
