Deep Learning of the Eddington Tensor in the Core-collapse Supernova Simulation

no code implementations27 Apr 2021 Akira Harada, Shota Nishikawa, Shoichi Yamada

We consider two kinds of DNNs: a conventional DNN named a component-wise neural network (CWNN) and a tensor-basis neural network (TBNN).

We find that low values of the electron fraction $Y_e$ produced by convective motions together with the appearance of light elements are critically important to give rise to the ELN crossing by enhancing the chemical potential difference between proton and neutron, and hence by mitigating the Fermi-degeneracy of $\nu_e$.
