Double Neutron Star Delay Times Across Cosmic Metallicities: The Role of Helium Star Progenitors

Abhishek Chattaraj, Jeff J. Andrews, Max Briel +5

Metallicity can play a significant role in massive binary evolution through its impact on the opacity within stellar interiors and wind-driven mass loss. In this work, we investiga…

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…

A new long gamma-ray burst formation pathway at solar metallicity

M. M. Briel, T. Fragos, O. S. Salafia +11

Context. Long gamma-ray bursts (LGRBs) are generally observed in low-metallicity environments. However, 10 to 20 per cent of LGRBs at redshift are associated with near-solar…

The effect of mass loss in models of red supergiants in the Small Magellanic Cloud

E. Zapartas, S. de Wit, K. Antoniadis +16

The rate and mechanism of mass loss of red supergiants (RSGs) remain poorly understood, especially at low metallicities. Motivated by the new empirical prescription by Yang et al.…
