Forming Double Neutron Stars using Detailed Binary Evolution Models with POSYDON: Comparison to the Galactic Systems
Abhishek Chattaraj, Jeff J. Andrews, Simone S. Bavera +14
With over two dozen detections in the Milky Way, double neutron stars (DNSs) provide a unique window into massive binary evolution. We use the POSYDON binary population synthesis c…
A binary merger product as the direct progenitor of a Type II-P supernova
Zexi Niu, Ning-Chen Sun, Emmanouil Zapartas +16
Type II-P supernovae (SNe II-P) are the most common class of core-collapse SNe in the local Universe and play critical roles in many aspects of astrophysics. Since decades ago theo…
HST Deep Upper Limits Rule Out a Surviving Massive Binary Companion to the Type Ic Supernova 2012fh
Benjamin F. Williams, Emmanouil Zapartas, Ori D. Fox +19
Current explanations of the mass-loss mechanism for stripped-envelope supernovae remain divided between single and binary progenitor systems. Here we obtain deep ultraviolet (UV) i…
The power of binaries on stripped-envelope supernovae across metallicity: uniform progenitor parameter space and persistently low ejecta masses, but subtype diversity
D. Souropanis, E. Zapartas, T. Pessi +9
Stripped-envelope supernovae (SESNe) originate from massive stars that lose their envelopes through binary interactions or stellar winds. The connection between SESN subtypes and t…
The Demographics of Binary Companions to Stripped-Envelope Supernovae: Confronting Observations with Population Synthesis
E. Zapartas, O. D. Fox, J. Su +15
Stripped-envelope supernovae (SESNe) mark the deaths of massive stars without hydrogen-rich envelopes. Most SESNe likely originate from binary systems where a companion stripped th…
POSYDON Version 2: Population Synthesis with Detailed Binary-Evolution Simulations across a Cosmological Range of Metallicities
Jeff J. Andrews, Simone S. Bavera, Max Briel +21
Whether considering rare astrophysical events on cosmological scales or unresolved stellar populations, accurate models must account for the integrated contribution from the entire…
