## "Conserved charges in general relativity and its implication on Oppenheimer-Volkoff equation"

We present a precise definition of a conserved quantity from an arbitrary

covariantly conserved current available in a general curved spacetime. This

definition enables us to define energy and momentum for matter by the volume

integral. As a result we can compute charges of well-known black holes just as

an electric charge of an electron in electromagnetism by the volume integration

of a delta function singularity. As a byproduct we show that the definition

leads to a correction to the known mass formula of a compact star in the

Oppenheimer-Volkoff equation.
