A gravitational wave detectable candidate Type Ia supernova progenitor
A gravitational wave detectable candidate Type Ia supernova progenitor
Type Ia supernovae, 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 other companion types capable of explaining the observed Ia rate, along with observations of …
