The present work is devoted to investigation of non-static plane symmetric universe filled with matter and anisotropic modified holographic Ricci dark energy components within the framework of a scalar-tensor theory formulated by Saez and Ballester (1986). To get the determinate solution of the model we have used scalar expansion proportional to the shear scalar, linearly varying deceleration parameter and energy density of modified holographic Ricci dark energy. We study the equation of state parameter (ωΛ), deceleration parameter (q), squared speed of sound (vs2) and ωΛ-ωΛ′ and r-s planes for our dark energy model. The equation of state parameter provides a quintom-like behavior of the universe. The r-s plane corresponds to ΛCDM limit, Chaplygin and phantom regions, whereas ωΛ-ωΛ′ trajectories correspond to both thawing and freezing regions. Keywords: Non-static, Plane symmetric, Ricci dark energy, Holographic dark energy, Saez-Ballester theory. |
