Supernovae in 2023 (review): breakthroughs by late observations
N Soker - arXiv preprint arXiv:2311.17732, 2023 - arxiv.org
I present a review of how late observations of supernovae, of the nebular phase, and much
later of supernova remnants (SNRs), and their analysis in 2023 made progress towards …

Mass-transferring binary stars as progenitors of interacting hydrogen-free supernovae
A Ercolino, H Jin, N Langer, L Dessart - arXiv preprint arXiv:2412.09893, 2024 - arxiv.org
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 to be …
