Abstract The masses and radii of non-rotating and rotating configurations of pure hadronic stars mixed with self-interacting fermionic asymmetric dark matter are calculated within the two-fluid formalism of stellar structure equations in general rela

Abstract In this work, the study of traversable wormholes in f(R) gravity with the function $$f(R)=R+\alpha R^n$$ f(R)=R+αRn , where $$\alpha $$ α and n are arbitrary constants, is taken into account. The shape function $$b(r)=\frac{r}{\exp (r-r_0)

Abstract In this work, static traversable wormholes are investigated in $$R^2$$ R2 gravity with logarithmic trace term T, where R denotes the Ricci scalar, and $$T=-\rho +p_r+2p_t>0$$ T=-ρ+pr+2pt>0 , the trace of the energy momentum tensor. The conn

Kim and Lee [Phys. Rev. D 63 (2001) 064014] studied charged wormholes and Morris–Thorne wormholes in the presence of scalar field using the concepts of general relativity. In this paper, we have also considered same wormholes affected with electric

Horizonless compact objects with light rings are becoming more popular in recent years for numerous motives. In this paper, the conditions under which the throat of a Morris–Thorne wormhole can act as an effective photon sphere are worked out. A sp

We explore an autonomous system analysis of dark energy models with interactions between dark energy and cold dark matter in a general systematic approach to cosmological fluids. We investigate two types of models such as local and non-local ones. In
