Accurate closed-form trajectories of light around a Kerr black hole using asymptotic approximants
Ryne J. Beachley, Morgan Mistysyn, Joshua A. Faber +2
Highly accurate closed-form expressions that describe the full trajectory of photons propagating in the equatorial plane of a Kerr black hole are obtained using asymptotic approxim…

An asymptotically consistent approximant for the equatorial bending angle of light due to Kerr black holes
Nathaniel S. Barlow, Steven J. Weinstein, Joshua A. Faber
An accurate closed-form expression is provided to predict the bending angle of light as a function of impact parameter for equatorial orbits around Kerr black holes of arbitrary sp…
