Supernova 1987 A and some Properties of Light, Exotic Particles

Abstract

The observation of a neutrino pulse from the supernova SN 1987A constrains the production of light, exotic particles in the proto neutron star. We give an overview over recently derived bounds on axion parameters, the strength of right handed weak currents, Dirac masses of neutrinos, and neutrino magnetic dipole moments. We also mention bounds on the neutrino-majoron coupling.
