Journal Article
Singularity-free anisotropic strange quintessence stars in f(R,ϕ,X) theory of gravity
2023
Overview
In this article, we present a detailed model of anisotropic quintessence stars in the hypothesis of
f
(
R
,
ϕ
,
X
)
gravity, where
R
is the Ricci scalar,
ϕ
represents the potential scalar and a kinetic term of
ϕ
is
X
. The Karori–Barua technique was used to solve the dynamical calculations in the
f
(
R
,
ϕ
,
X
)
hypothesis using an anisotropic fluid and quintessence field. We observed that all of the answers we found are independent of focal peculiarity and possibly steady. The masses and radii of compact stars like Her X-1, SAX J1808.4-3658, and 4U 1820-30 were utilized to compute the value of obscure constants in the Krori and Barua metric. Graphical plots have been created for the fluid parameters density, radial, transverse, and anisotropy factors. To talk about the model’s regularity, the first and second derivatives of density and radial pressure have been assessed. The stability of the developed model is determined utilizing radial sound speed velocity and tangential sound speed velocity. The true bounds of the stars such as anisotropy, intensity, and redshift have been thoroughly investigated.
