论文摘要
中微子风味振荡对中微子束驱动的磁质体中的磁流失动力学（MHD）波的传播的影响。使用中微子MHD模型，得出了一般分散关系，该关系表现出MHD波的共振相互作用，不仅与中微子束，而且还与中微子风味振荡。发现后者有助于波散，并增强斜磁波不稳定性的大小。但是，剪切alfv {é} n波不受中微子束和中微子风味振荡的影响。对于高中微子数量密度和/或强磁场方案中相对长的波长扰动，磁波不稳定性的幅度的这种增强可能是显着的，这给出了令人信服的II核心曲折超级新星爆炸的令人信服的机制。
The influence of neutrino flavor oscillations on the propagation of magnetohydrodynamic (MHD) waves and instabilities is studied in neutrino-beam driven magnetoplasmas. Using the neutrino MHD model, a general dispersion relation is derived which manifests the resonant interactions of MHD waves, not only with the neutrino beam, but also with the neutrino flavor oscillations. It is found that the latter contribute to the wave dispersion and enhance the magnitude of the instability of oblique magnetosonic waves. However, the shear-Alfv{é}n wave remains unaffected by the neutrino beam and neutrino flavor oscillations. Such an enhancement of the magnitude of the instability of magnetosonic waves can be significant for relatively long-wavelength perturbations in the regimes of high neutrino number density and/or strong magnetic field, giving a convincing mechanism for type-II core-collapse supernova explosion.
