based on an arbitrary function f (T, B) which depends on the scalar torsion T and the
boundary term B. To do this, we first find new perturbed spherically symmetric solutions
around Schwarzschild for different power-law forms of the arbitrary Lagrangian. Then, for
each model we calculated the photon sphere, perihelion shift, deflection of light, Cassini
experiment, Shapiro delay and the gravitational redshift. Finally, we confront these …
