Time Like Geodesics of Regular Black Holes with Scalar Hair
P. A. González, Marco Olivares, Eleftherios Papantonopoulos +1
We investigate timelike geodesics in asymptotically flat regular black holes supported by a phantom scalar field characterized by a scalar charge . This parameter removes the ce…

Massive Particle Motion Around Horndeski Black Holes
D. A. Carvajal, P. A. González, Marco Olivares +2
The time-like structure of the four-dimensional asymptotically flat Horndeski black holes is studied in detail. Focusing on the motion of massive neutral test particles, we constru…

Study of Null Geodesics and their Stability in Horndeski Black Holes
D. A. Carvajal, P. A. González, Marco Olivares +2
We study the motion of particles in the background of a scalar-tensor theory of gravity in which the scalar field is kinetically coupled to the Einstein tensor and we present the n…
