NEUTRINO OSCILLATIONS AT SUPERNOVA CORE BOUNCE GENERATE THE STRONGEST GRAVITATIONAL-WAVE BURSTS
International Journal of Modern Physics D
During the core bounce of a supernova collapse resonant active-to-active (ν_a →ν_a), as well as active-to-sterile (ν_a →ν_s) neutrino (ν) oscillations can take place. Besides, over this phase weak magnetism increases antineutrino (ν̅) mean free paths, and thus its luminosity. Because the oscillation feeds mass-energy into the target ν species, the large mass-squared difference between species (ν_a →ν_s) implies a huge amount of power to be given off as gravitational waves (L_GWs∼ 10^49ergdoi:10.1142/s0218271804005456 fatcat:b4alvxmq6fbc7e5hoynirwgxfq
