Abstract

When hypothetical neutrino secret interactions ($\nu$SI) are large, they form a fluid in a supernova (SN) core, flow out with sonic speed, and stream away as a fireball. For the first time, we solve all steps, systematically using relativistic hydrodynamics, although a simplified source model. The impact on SN physics and the neutrino signal is remarkably small. Even for complete thermalization within the fireball, the observable spectrum barely changes. Small energy-transfer modifications may affect the neutrino-driven explosion mechanism, but on present evidence are not ruled in or out. One potentially large effect beyond our study is quick deleptonization if $\nu$SI violate lepton number.
