Cylindrical Jeans equations in a rotating frame
= Cylindrical Jeans equations in a rotating frame
The first moments of the <rotating-frame collisionless Boltzmann equation> express radial and azimuthal momentum balance. Coriolis terms enter as $-2\Omega_b\rho\langle v_\phi\rangle$ and $+2\Omega_b\rho\langle v_R\rangle$ on the left. Geometric stress terms are $\rho(\langle v_R^2\rangle-\langle v_\phi^2\rangle)/R$ and $2\rho\langle v_Rv_\phi\rangle/R$. Second moments include random stress and streaming flux.
