| 英文摘要 | We quantify the impact of strong magnetic fields (assuming B = B-0 . r(0)(3)/r(3) with B-0 greater than or similar to 10(16) G) on the neutrino transport in core-collapse supernovae (CCSNe). Magnetic fields quantize the momenta of electrons and positrons, resulting in an enhanced absorption cross section for low-energy neutrinos and suppressed chemical potentials for e(+/-). We include these changes in the M1 scheme for neutrino transport and perform 1D CCSNe simulations with GR1D. The increased low-energy cross sections reduce the (nu) over bar (e) mean energy < E-(nu) over bare > while elevating the neutrino number luminosities L-nu for both nu(e) and v(e) due to the lowerenergy weighted spectra. The reduction of chemical potential enhances the (nu) over bar (e) emission while suppressing that of nu(e), thereby driving an increase in the electron fraction behind the stalled shock at similar to 30-100 km. This further amplifies (E-nu e) through an increased electron density. Consequently, magnetic fields amplify L-nu e by increasing both L-nu e and < E-nu e >, whereas for (nu) over bar (e), the rise in L-(nu) over bare is offset by a decreased < E-(nu) over bare >, leading to a minimal change in L-(nu) over bare. A systematic parameter scan of dipole field configurations suggests that, for r(0) > 30 km, (E-(nu) over bare) is significantly suppressed and L nu e is enhanced if B-0 >= 2.7 x 10(16) G. These magnetic effects become negligible for B-0 below similar to 7.4 x 10(15) G. |
