Description
We discuss the dark photon and $Z^\prime$ emission from supernova. We evaluate the production amplitude for the dark photon and $Z^\prime$ via nucleon bremmstrahlung process $NN\rightarrow NN Z^\prime$. Finally, We derive the SN1987A constraints on dark photon and $Z^\prime$ from the stellar cooling argument.
