A Gravitational-wave-detectable Candidate Type Ia Supernova Progenitor
Type Ia supernovae (SNe Ia), critical for studying cosmic expansion, arise from thermonuclear explosions of white dwarfs, but their precise progenitor pathways remain unclear. Growing evidence supports the "double-degenerate scenario," where two white dwarfs interact. The absence of nondegenerate companions capable of explaining the observed SN Ia
