Query: Singularity-free nonexotic compact star in $f(R,T)$ gravity   In the present work, we have searched the existence of anisotropic and
non-singular compact star in the $f(R,T)$ gravity by taking into account the
non-exotic equation of state (EoS). In order to obtain the solutions of the
matter content of compact object, we assume the well known barotropic form of
EoS that yields the linear relation between pressures and energy density. We
propose the existence of non-exotic compact star which shows the validation of
energy conditions and stability with in the $f(R,T)$ extended theory of gravity
perspective. The linear material correction in the extended theory the matter
content of compact star remarkably able to satisfies energy condition. We
discuss various physical features of compact star and show that proposed model
of stellar object satisfies all regularity conditions and is stable as well as
singularity-free.
