SUMMARY
The discussion focuses on the incorporation of angular momentum into the stress-energy tensor for rotating objects, particularly neutron stars. It establishes that the components T21, T31, and T32 are relevant for angular momentum, while T0k terms represent energy flow in rotating systems. The example provided for rotational kinetic energy of a neutron star with a frequency of 1000 Hz utilizes the formula E_k=1/2·0.4mr^2·(fπ²) to illustrate the calculation. Additionally, the application of shear stress quantities T12, T13, and T23 is questioned, indicating their relevance in specific scenarios.
