Thanks for your quick reply. Maybe I didn't express myself so well. Let's start from stress-energy tensor for sphere, which can be written as T^{ab} = (\rho + p) u^a u^b + p g^{ab}, but in rest frame where sphere doesn't rotate, it's only T^{00} element that's nonzero (I think so!). But now...

Hy. Can somebody please show me the way, how to transform stress-energy tensor for sphere in rest frame to stress-energy tensor in rotating frame using Lorentz transformations?
