Chaotic lensing around boson stars and Kerr black holes with scalar hair
Chaotic lensing around boson stars and Kerr black holes with scalar hair
In a recent letter, arXiv:1509.00021, it was shown that the lensing of light around rotating boson stars and Kerr black holes with scalar hair can exhibit chaotic patterns. Since no separation of variables is known (or expected) for geodesic motion on these backgrounds, we examine the 2D effective potentials for …
