چکیده
We investigate the $f$-mode oscillation of dark matter admixed hyperon star within relativistic Cowling approximation. The macroscopic properties are calculated with mean-field equation states by assuming that particles inside star. frequencies (only for $l=2$) four different neutron states. also check effects hyperons/dark and hyperons on oscillations varying astrophysical quantities such as mass ($M$), radius ($R$), compactness ($M/R$), surface red-shift (${Z}_{s}$), average density ($\overline{\ensuremath{\rho}}$), dimensionless tidal deformability ($\mathrm{\ensuremath{\Lambda}}$) Significant changes have been seen in without or $\mathrm{hyperons}+\mathrm{dark}$ matter. Substantial correlations observed between canonical $\mathrm{\ensuremath{\Lambda}}$ (${f}_{1.4}\ensuremath{-}{\mathrm{\ensuremath{\Lambda}}}_{1.4}$) maximum (${f}_{\mathrm{max}}\ensuremath{-}{\mathrm{\ensuremath{\Lambda}}}_{1.4}$).

We present results from Brueckner–Hartree–Fock calculations for β-stable neutron star matter with nucleonic and hyperonic degrees of freedom, employing the most recent parametrizations of the baryon-baryon interaction of the Nijmegen group. It is found that the only strange baryons emerging in β-stable matter up to total baryonic densities of 1.2 fm −3 are Σ − and Λ. The corresponding equations...

cement is an essential ingredient in the concrete buildings. for production of cement considerable amount of fossil fuel and electrical energy is consumed. on the other hand for generating one tone of portland cement, nearly one ton of carbon dioxide is released. it shows that 7 percent of the total released carbon dioxide in the world relates to the cement industry. considering ecological issu...
