In theories with large extra dimensions, supernova (SN) cores are powerful sources of Kaluza-Klein (KK) gravitons. A large fraction of these massive particles are gravitationally retained by the newly born neutron star (NS). The subsequent slow KK decays produce potentially observable gamma rays and heat the NS. We here show that the back-absorption of the gravitationally trapped KK gravitons does not significantly change our previous limits. We calculate the graviton emission rate in a nuclear… Expand
