Observations on the massive particle surface method
Ednaldo L. B. Junior, José Tarciso S. S. Junior, Francisco S. N. Lobo +3
The geodesic method has played a crucial role in understanding the circular orbits generated by compact objects, culminating in the definition of the photon sphere, which was later…
A regular metric does not ensure the regularity of spacetime
Manuel E. Rodrigues, Henrique A. Vieira
In this paper we try to clarify that a regular metric can generate a singular spacetime. Our work focuses on a static and spherically symmetric spacetime in which regularity exists…
Is it possible to distinguish between different black hole solutions using the Shapiro time delay?
Ednaldo L. B. Junior, Manuel E. Rodrigues, Henrique A. Vieira
In this paper we propose to use Shapiro time delay as a tool to distinguish between different black hole solutions. We calculate the analytic Shapiro time, using first-order expans…
