Static Spherically Symmetric Black Holes in Weak f(T)-Gravity

With the advent of gravitational wave astronomy and first pictures “shadow” central black hole our milky way, theoretical analyses holes (and compact objects mimicking them sufficiently closely) have become more important than ever. The near future promises detailed information about observable candidates. This could lead to advances on constraints or evidence for modifications general relativity. More precisely, we are studying influence weak teleparallel perturbations relativistic vacuum spacetime geometries in spherical symmetry. We find most family spherically symmetric, static solutions theory, which candidates describing emerge as Schwarzschild hole. compare findings results static, symmetric gravity discussed literature, by comparing predictions classical observables such photon sphere, perihelion shift, light deflection, Shapiro delay. On basis these observables, demonstrate that among found, there exist much weaker bounds those found earlier. Finally, move a discussion how Hawking evaporation spacetimes.
