摘要: The question why and how core-collapse supernovae (SNe) explode is one of the central most long-standing riddles stellar astrophysics. A solution crucial for deciphering SN phenomenon, predicting observable signals such as light curves spectra, nucleosynthesis, neutrinos, gravitational waves, defining role SNe in evolution galaxies, explaining birth conditions properties neutron stars (NSs) stellar-mass black holes. Since formation compact remnants releases over hundred times more energy neutrinos than explosion, can be decisive agents powering outburst. According to standard paradigm neutrino-driven mechanism, transfer by intense neutrino flux medium behind stagnating core-bounce shock, assisted violent hydrodynamic mass motions (sometimes subsumed term "turbulence"), revives outward shock motion thus initiates blast. Because weak coupling region this deposition, detailed, multidimensional models including transport a wide variety physics are needed assess viability mechanism. Owing advanced numerical codes increasing supercomputer power, considerable progress has been achieved our understanding physical processes that have act concert success explosions. First studies begin reveal observational implications avenues test theoretical picture data from individual but also population-integrated observables. While will further refined, real breakthrough expected through next Galactic SN, when waves used probe deep inside dying star. (abridged)
