Zepei Xing, Tassos Fragos, Emmanouil Zapartas +12
The three dynamically confirmed wind-fed black hole high-mass X-ray binaries (BH-HMXBs) are suggested to all contain a highly spinning black hole (BH). However, based on the theori…
On the origin of mixed morphology supernova remnants: Linking their properties to the evolution of a red supergiant progenitor star
Alexandros Chiotellis, Emmanouil Zapartas, Dominique M. -A. Meyer
Mixed-morphology supernova remnants (MMSNRs) are characterized by a shell-like morphology in the radio and centrally-peaked thermal emission in the X-ray band. The nature of this p…
Considering the Single and Binary Origins of the Type IIP SN 2017eaw
K. Azalee Bostroem, Emmanouil Zapartas, Brad Koplitz +3
Current population synthesis modeling suggests that 30-50% of Type II supernovae originate from binary progenitors, however, the identification of a binary progenitor is challengin…
From ZAMS to Merger: Detailed Binary Evolution Models of Coalescing Neutron Star-Black Hole Systems at Solar Metallicity

Neutron star black hole (NSBH) merger events bring us new opportunities to constrain theories of stellar and binary evolution, and understand the nature of compact objects. In…
Exploring the nature of ultra-luminous X-ray sources across stellar population ages using detailed binary evolution calculations
Devina Misra, Konstantinos Kovlakas, Tassos Fragos +8
Ultra-luminous X-ray sources (ULXs) are sources observed to exceed the Eddington limit of a stellar-mass black hole (BH). A fraction of ULX sources show X-ray pulses which are evid…

Simone S. Bavera, Tassos Fragos, Emmanouil Zapartas +11
The maximum mass of black holes formed in isolated binaries is determined by stellar winds and the interactions between the binary components. We consider for the first time fully…
A Black Hole Kicked At Birth: MAXI J1305-704
Chase Kimball, Sam Imperato, Vicky Kalogera +12
When a compact object is formed in a binary, any mass lost during core collapse will impart a kick on the binary's center of mass. Asymmetries in this mass loss or neutrino emissio…
A population of Type Ibc supernovae with massive progenitors; broad lightcurves not uncommon in (i)PTF
E. Karamehmetoglu, J. Sollerman, F. Taddia +9
If high-mass stars (>20-25 Msun) are the progenitors of stripped-envelope (SE) supernovae (SNe), their massive ejecta should lead to broad, long-duration lightcurves (LCs). Instead…
