Abstract: (AIP)
During supernova core collapse and bounce resonant active‐to‐active, as well as active‐to‐sterile, neutrino (v) oscillations can take place. Over this phase weak magnetism increases antineutrino mean free paths, and thus its luminosity. Because oscillations feed mass‐energy into the target v species, the large mass‐squared difference between v states implies a huge amount of power to be given off as gravitational waves (GWs) due to the spin‐rotation and spin‐magnetic coupling driven v anisotropic flow, which is coherent over the oscillation length. The spacetime strain produced is about two orders of magnitude larger than those from v difussion or neutron star matter anisotropies. GWs observatories as LIGO, VIRGO, GEO‐600, TAMA‐300, etc., can search for these bursts far out to the VIRGO cluster of galaxies.- 14.60.Pq
