| dc.description | If neutrino flavor changes really exist, to say: $μ$-neutrino oscillating into a sterile neutrino, then, it can be expected that due to neutrino oscillations and non-spherical distortion of the resonance surface induced by the magnetic field, some asymmetric emission of sterile neutrinos can occur during the protoneutron star formation at the onset of a supernova core-collapse. Assuming no strong suppression of the oscillations, the non-spherical huge neutrino energies released, ($\sim 10^{53-54} erg$), together with the proto-neutron star rapid rotation, may trigger powerful bursts of gravitational waves by the time neutrino flavor conversions ensue. I show here that these bursts are detectable by the new generation of gravitational-wave detectors as LIGO, VIRGO and TIGAs for distance scales $\sim 10 kpc$. It is also argued that the general relativity requirement of an ellipsoidal axisymmetric core at maximum gravitational-wave emission induced by $ν$-luminosity can properly be afforded by the neutrino-sphere geometry when the oscillations onset. The connection of neutrino oscillations with the supernova asymmetry and bi-polar jets ejecta is shown naturally to appear in this scenario. | |
