Published in 2020 at "Astrophysics and Space Science"

DOI: 10.1007/s10509-020-3734-6

Abstract: The present article is an attempt to arrive at a new solution for an isotropic charged compact star model admitting Karmarkar’s condition in the context of general relativity. For this we chose a new metric… read more here.

Published in 2019 at "Monthly Notices of the Royal Astronomical Society"

DOI: 10.1093/mnras/stz3041

Abstract: We present observations with the Cosmic Origins Spectrograph onboard the Hubble Space Telescope of eight compact star-forming galaxies at redshifts z = 0.02811–0.06540, with low oxygen abundances 12 + log(O/H) = 7.43–7.82 and extremely high emission-line flux ratios O32 = [O iii]… read more here.

Published in 2020 at "Progress of Theoretical and Experimental Physics"

DOI: 10.1093/ptep/ptaa014

Abstract: We study compact star made of degenerate hidden sector nucleons which will be a candidate for cold dark matter. A hidden sector like QCD is considered, and as the low energy effective theory we take… read more here.

Published in 2019 at "Physical Review D"

DOI: 10.1103/physrevd.100.084023

Abstract: We present a physically plausible solution representing Einstein's cluster mimicking the behaviors of compact star in the context of teleparallel equivalent of general relativity. The Teleparallel gravity (TEGR) is an alternative formulation of gravity which… read more here.

Published in 2021 at "Physical Review D"

DOI: 10.1103/physrevd.104.043020

Abstract: We study the anomalous mass defects in the first (ascendant) branch of stellar sequences of static strange stars. We employ the nonperturbative equation of state derived in the framework of the Field Correlator Method to… read more here.

Published in 2021 at "International Journal of Geometric Methods in Modern Physics"

DOI: 10.1142/s0219887821500602

Abstract: The purpose of this work is to present stellar models for anisotropic matter distribution in the framework of f(T) gravity with torsion scalar T. In this regard, we use the interior geometry of Tol... read more here.

Published in 2019 at "Universe"

DOI: 10.3390/universe5070174

Abstract: The equation of state provided by effective models of strongly interacting matter should comply with the restrictions imposed by current astrophysical observations of compact stars. Using the equation of state given by the (axial-)vector meson… read more here.
