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

@article{Pfeifer2021StaticSS, title={Static Spherically Symmetric Black Holes in Weak f(T)-Gravity}, author={Christian Pfeifer and Sebastian Schuster}, journal={Universe}, year={2021}, volume={7}, pages={153} }

With the advent of gravitational wave astronomy and first pictures of the “shadow” of the central black hole of our milky way, theoretical analyses of black holes (and compact objects mimicking them sufficiently closely) have become more important than ever. The near future promises more and more detailed information about the observable black holes and black hole candidates. This information could lead to important advances on constraints on or evidence for modifications of general relativity…

It is proved that by imposing that the metric functions are the reciprocal of each other (grr = 1/gtt ), the f(Q) gravity theory reduces to the symmetric teleparallel equivalent of general relativity (plus a cosmological constant), and the metric takes the (Anti)de-Sitter-Schwarzschild form.
