论文摘要
已知巨大的电磁场存在于超新星动力学的后期。因此，在这种情况下处理电动力学时，可能会出现探测非线性理论的可能性。爱因斯坦场方程最小化与任意的非线性拉格朗日式电动力学的拉格朗日，在缓慢旋转的制度中解决了，即$ a << m $（黑洞的质量），以$ a/m $ $ a/m $。我们使用Born-Infeld Lagrangian将获得的结果与Maxwellian同行进行比较。我们专注于中微子风味振荡的天体物理学（$ν_e\toν_{μ，τ} $）和Spin-Flip（$ν_l\toν_r$），以及计算的计算电子分数$ y_e $，因此与R-Process相差有很大的不同，因此与R-Process相差有很大的不同，因此可能会差异与标准的Electrysics相差。
Huge electromagnetic fields are known to be present during the late stages of the dynamics of supernovae. Thus, when dealing with electrodynamics in this context, the possibility may arise to probe nonlinear theories. The Einstein field equations minimally coupled to an arbitrary nonlinear Lagrangian of electrodynamics are solved in the regime of slow rotation, i.e. $a << M$ (black hole's mass), up to first order in $a/M$. We use Born-Infeld Lagrangian to compare the obtained results with Maxwellian counterpart. We focus on the astrophysics of neutrino flavor oscillations ($ν_e\toν_{μ, τ}$) and spin-flip ($ν_L\toν_R$), as well as on the computation of that the electron fraction $Y_e$, hence the r-processes, which may significantly differ with respect to the standard electrodynamics.
