Compact stars admitting Finch-Skea symmetry in the presence of various matter fields

In the present study, we investigate the anisotropic stellar solutions admitting Finch-Skea symmetry(viable and non-singular metric potentials) in the presence of some exotic matter fields, such as Bose-Einstein Condensate(BEC) dark matter, the Kalb-Ramond fully anisotropic rank-2 tensor field from the low-energy string theory effective action, and the gauge field imposing U(1)symmetry. Interior spacetime is matched with both Schwarzchild and Reissner-N?rdstrom vacuum spacetimes for BEC, KB, and gauge fields. In addition, we study the energy conditions, Equation of State(EoS), radial derivatives of energy density and anisotropic pressures, Tolman-OppenheimerVolkoff equilibrium condition, relativistic adiabatic index, sound speed, and surface redshift. Most of the aforementioned conditions are satisfied. Therefore, the solutions derived in the current study lie in the physically acceptable regime.
