Description

We investigate the finite temperature and density effects on the electromagnetic properties of neutrinos. For a Standard Model neutrino we find a left-handed effective charge and a chirality flipping term associated with the longitudinal photon exchange. We find that in the supernova the chirality flipping rate is two orders of magnitude larger than the previous estimates using the vacuum magnetic moment. (orig.)
