Rings and images of Horndeski hairy black hole illuminated by various thin accretions
XJ Wang, XM Kuang, Y Meng, B Wang, JP Wu - Physical Review D, 2023 - APS
In this paper, we analyze the light rays around a static hairy black hole in Horndeski gravity
with the use of ray-tracing procedure. We find that a stronger Horndeski hairy parameter …
