Key Equations

$$\boxed{L_{acc} = \frac{GM\dot{M}}{R} = \eta \dot{M} c^2}$$
$$\frac{\partial}{\partial t}(\Sigma r^2 \Omega) + \frac{1}{r}\frac{\partial}{\partial r}(\Sigma r^3 v_r \Omega) = \frac{1}{r}\frac{\partial}{\partial r}(r^2 \nu \Sigma r \frac{d\Omega}{dr})$$
$$T_{eff}(r) = \left(\frac{3GM\dot{M}}{8\pi \sigma_{SB} r^3}\right)^{1/4} \propto r^{-3/4}$$
$$-i\omega \delta v_\phi + \frac{\kappa^2}{2\Omega}\delta v_r = -\frac{k_z^2 v_A^2}{-i\omega}\delta v_\phi$$

Equations are rendered with MathJax in the PDF with professional LaTeX typesetting.
