Description

Sterile neutrinos can be produced through mixing with active neutrinos in the hot and dense core of a collapsing supernova (SN). The standard SN bounds on the active-sterile mixing ($\theta$) arise from the SN1987A energy-loss argument. In this talk, I will discuss a novel and stringent bound on $\theta$ arising from the energy deposition through the decays of sterile neutrinos inside the SN envelope.
