Probing Lorentz-violating effects via precession and accretion disk images of a rotating bumblebee black hole
r˙=−Veff(r,π/2)/grr.\dot{r}=-\sqrt{V_{\text{eff}}(r,\pi/2)/g_{rr}}. (17) Here we have chosen infalling timelike geodesics (r˙ 0\dot{r} 0), as they are more physically plausible for constructing accretion disk models in the subsequent analysis. In our model, we are interested in bound circular orbital motion, for which the conditionsVeff(r,π/2)=0V_{\...
