Parametrized post-Newtonian limit of generalized scalar-nonmetricity theories of gravity
Kai Flathmann, Manuel Hohmann
In this article we calculate the post-Newtonian limit of a general class of scalar-nonmetricity theories of gravity. The action is assumed to be a free function of the nonmetricity…
Post-Newtonian limit of generalized symmetric teleparallel gravity
Kai Flathmann, Manuel Hohmann
In this article we analyze the post-Newtonian approximation of a generalization of the symmetric teleparallel gravity with the help of the parameterized post-Newtonian (PPN) formal…
Geodesic equations for particles and light in the black spindle spacetime
Kai Flathmann, Noa Wassermann
In this paper we derive the geodesic equation for massive particles and light for the black spindle spacetime. The solution for light can be formulated in terms of the Weierstraß {…
Post-Newtonian limit of generalized scalar-torsion theories of gravity
Kai Flathmann, Manuel Hohmann
In this article we derive the post-Newtonian limit of a class of teleparallel theories of gravity, where the action is a free function of the Torsion scalar and sc…
Photon sphere and perihelion shift in weak gravity
Sebastian Bahamonde, Kai Flathmann, Christian Pfeifer
Among modified theories of gravity, the teleparallel gravity is an intensively discussed modelin the literature. The best way to investigate its viabilityis to derive observ…
Analytic solutions of the geodesic equation for Reissner-Nordström-(anti-)de Sitter black holes surrounded by different kinds of regular and exotic matter fields
Arindam Kumar Chatterjee, Kai Flathmann, Hemwati Nandan +1
The purpose of this study is the derivation of the equation of motion for particles and light in the spacetime of Reissner-Nordström-(anti-)de Sitter black holes in the background…
