Abstract : The discovery of a Binary Neutron Star (BNS) merger and an associated optical transient AT2017gfo emerging from the radioactive decay of r-process elements confirmed the role of BNS mergers in the production of heavy elements in the universe. Theoretical calculations of such optical transients, named Kilonovae, were made decades ago and AT2017gfo broadly agreed with these predictions. Kilonova ejecta decelerates once it accumulates enough interstellar material and becomes a Kilonova Remnant (KNR). Due to their faintness, a KNR detection can only be made in our Galaxy. In this paper, we calculate the possible rate of kilonova remnants in our Galaxy and discuss their detectability and ways of identifying them.
