Hybrid compact stars with finite strange quark mass and dark energy: implications for astrophysical observations

Rohit Roy, Koushik Ballav Goswami, Debadri Bhattacharjee +1

In this work, a detailed investigation of compact stars composed of deconfined quark matter with finite strange quark mass ( $m_{s} \neq = 0$ ) admixed with dark energy is presented. The…

Influence of density-dependent bag function $B (n)$ on strange stars for non-zero strange quark mass ( $m_{s} \neq = 0$ ) in $f (R, T)$ gravity consistent with observational validation

Rohit Roy, Debadri Bhattacharjee, Koushik Ballav Goswami +1

In this work, a new class of solution of the Einstein field equation for an isotropic strange star using the modified Mak-Harko type density profile along with the equation of stat…

QCD coupling constant ( $I^\pm_{c}$ ) and nonzero value of strange quark mass ( $m_{s} \neq = 0$ ) dependent stable stellar structure admitting observational results

R Roy, K B Goswami, P K Chattopadhyay +1

This work discuses the effect of the QCD coupling constant ( $I^\pm_{c}$ ) on various physical properties of compact stars in the framework of the Tolman IV potential admitting the equati…
