Description
A new expression for the baryon number of a uniformly rotating cold star is derived within the framework of general relativity. It gives the baryon number, in terms of integrals involving the energy density and the pressure, rather than the baryon-number density. The expression is used to obtain a relation between the star mass, its baryon number, and its moment of inertia, in terms of the angular velocity, the redshift at the pole, and the ratio of the proper volume averages of the pressure and the energy density
