I'm currently looking at stress-energy tensors and while I understand that T(adsbygoogle = window.adsbygoogle || []).push({}); _{00}is density and T_{11}, T_{22}and T_{33}are pressure, where does angular momentum fit in this? I'm assuming the quantities T_{21}, T_{31}and T_{32}might have something to do with this. For example, how would you incorporate the rotational kinetic energy of a neutron star with a frequency of 1000 Hz? [itex](E_k=1/2\cdot 0.4mr^2\cdot (f\pi2)^2)[/itex] Also, when might the shear stress quantities, T_{12}, T_{13}and T_{23}apply? Cheers.
