Optical Characteristics and Frequency Shifts of Quartic Wormholes in f(T,τ) Gravity
Abstract
This work explores traversable wormhole solutions characterized by a quartic inverse-power density profile within f(T,τ) gravity. A specific inverse-power density profile, characterized by proportional to 1/r4 is introduced to establish the corresponding exact form of the shape function. The derived configuration exhibits all the necessary geometrical features of a traversable wormhole, such as throat formation, flaring-out behavior, and acceptable asymptotic characteristics. To gain further insight into the matter sector, we analyze the corresponding radial profiles of the energy density and pressure components. The throat region is characterised by negative radial pressure and null energy condition violation, both of which are relevant to the exotic matter content of the wormhole solution. To examine the lensing characteristics of the obtained spacetime, we employ the Gauss-Bonnet formalism to evaluate the gravitational deflection angle. Our findings indicate that the parameters γ and ρ0 exert a considerable influence on the resulting light trajectories. The perturbative behavior of the obtained configuration is investigated within the scalar and electromagnetic field sectors. Subsequently, a novel electromagnetic potential is introduced to examine its influence on the radial variation of the red-blue shifts characteristics. Our findings establish a unified picture of the geometrical, perturbative, and optical characteristics of quartic density-supported wormholes.
