The central region of Supernovae are one of the hottest and densest regions in the Universe. Due to the high temperatures, particles with sub-GeV masses can be copiously produced if they have non-negligible couplings to the Standard Model. If dark matter has sub-GeV mass it will be produced in the hot Supernovae core and it will have sufficiently large momenta to be detectable in direct detection experiments. In this talk I discuss the sensitivity of current and future Xenon based direct detection experiments to a simplified model of dark matter which interacts with the Standard Model via the dark photon portal.
