This paper discusses the gravitational collapse of dynamical self-gravitating
fluid distribution in $f(mathcal{R},mathcal{T},mathcal{Q})$ gravity, where
$mathcal{Q}=mathcal{R}_{varphivartheta}mathcal{T}^{varphivartheta}$. In
this regard, we assume a charged anisotropic spherical geometry involving
dissipation flux and adopt standard model of the form
$mathcal{R}+Phisqrt{mathcal{T}}+Psimathcal{Q}$, where $Phi$ and $Psi$
symbolize real-valued coupling parameters. The Misner-Sharp as well as
M”{u}ler-Israel Stewart mechanisms are employed to formulate the corresponding
dynamical and transport equations. We then interlink these evolution equations
which help to study the impact of state variables, heat dissipation, modified
corrections and charge on the collapse rate. The Weyl scalar is further
expressed in terms of the modified field equations. The necessary and
sufficient condition of conformal flatness of the considered configuration and
homogeneous energy density is obtained by applying some constraints on the
model along with disappearing charge and anisotropy. Finally, we discuss
different cases to investigate how the spherical matter source is affected by
the charge and modified corrections.
This paper explores the gravitational collapse of a dynamical self-gravitating fluid distribution in $f(mathcal{R},mathcal{T},mathcal{Q})$ gravity, where $mathcal{Q}=mathcal{R}_{varphivartheta}mathcal{T}^{varphivartheta}$. The study focuses on a charged anisotropic spherical geometry with dissipation flux, utilizing the standard model $mathcal{R}+Phisqrt{mathcal{T}}+Psimathcal{Q}$, where $Phi$ and $Psi$ are real-valued coupling parameters.
To formulate the dynamical and transport equations, the Misner-Sharp and M”{u}ler-Israel Stewart mechanisms are employed. The evolution equations are then interconnected to examine the impact of state variables, heat dissipation, modified corrections, and charge on the collapse rate. Additionally, the Weyl scalar is expressed in terms of the modified field equations.
The paper also derives the necessary and sufficient condition for conformal flatness of the considered configuration and homogeneous energy density by applying constraints on the model, including the absence of charge and anisotropy.
Lastly, the study explores various cases to investigate how the charge and modified corrections affect the spherical matter source.
