In contrast, electron neutrinos and antineutrinos ($\\nu_e$ and $\\bar\\nu_e$) are frequently absorbed and produced in charged-current mediated reactions with nucleons. Therefore the emergent $\\nu_e$ and $\\bar\\nu_e$ originate from layers with lower temperatures further out in the star and are emitted with much lower characteristic spectral temperatures.
