The binary progenitors of core-collapse supernovae

[摘要] Core-collapse supernovae are thought to be the death explosions of massive stars. Mass and metallicity have been regarded as the primary drivers in stellar evolution, including in the evolution of the progenitor stars of supernovae. However, the diversity of supernova explosions cannot seem to be explained by these two parameters only, furthermore there have been evidences that some supernovae are produced by binary progenitors. This supports the current paradigm that binarity plays an important role in the evolution of massive stars.
