  In this paper, we assess different charged self-gravitating stellar models
possessing anisotropic matter source in the background of $f(G,T)$ gravity. For
this purpose, we choose a well-known model of this gravity, i.e.,
$f(G,T)=G^2+\varrho T$, where $\varrho$ stands for the coupling constant. The
modified field equations are developed using MIT bag model equation of state,
and their solution is found with the help of Tolman IV ansatz which contains
three unknown constants. This solution is further exploited to examine the
graphical behavior of Her X-I, PSR J1614-2230, 4U1820-30 and LMC X-4 celestial
objects. We assume two different values of charge to figure out the pressure
constituents, energy density, anisotropy and energy constraints graphically. We
also discuss compactness, mass and redshift parameters. Finally, we explore
stability of the considered stars through two different methods. It is
concluded that all the star candidates are viable as well as stable for
$\mathcal{Q}=0.1$. For the larger charge, the viable behavior is also observed
for all stars but PSR J1614-2230 shows unstable trend.
