摘要：

The mass parameters of compact objects such as boson stars, Schwarzschild, Reissner-Nordstrom, and Kerr black holes are computed in terms of the measurable redshift-blueshift (z(red), z(blue)) of photons emitted by particles moving along circular geodesics around these objects and the radius of their orbits. We find bounds for the values of (z(red), z(blue)) that may be observed. For the case of the Kerr black hole, recent observational estimates of Sgr A* mass and rotation parameter are employed to determine the corresponding values of these red-blue shifts.
