Relativistic model foranisotropicspheres in f(R,T) gravity via Karmarkar condition

Our present work is devoted to investigate the existence of acompact stellar configuration model in the framework off(R,T)gravity theory, whereRandTdenote the Ricci scalar andtrace of energy-momentum tensor, respectively. Here, we havedeveloped a setup using a well-known Karmarkar condition andobtainedawell-behavedembeddingclass-onesolutionwithspe-cific linear functionf(R,T)=R+2 chi T, where chi is the couplingconstant. We obtain a specific form of differential equation byusingthisconditionthatshowedaconnectionbetweene lambda ande nu.With the viability of our stellar model, we have checked all thephysical parameters such as density, pressure, speed of sound,TOV equation, redshift, etc. of compact stars like RX J1856-37,4U1538-52,SAXJ1808.4-3658,EXO1785-248,PSRJ1903+327,and Vela X-1 which are conferred in tables and graphs. Andthe observation suggested, our solution for compact stars usingKarmarkar condition in the background off(R,T) has shownmore consistency and the results are fair and appealing.
