General Relativistic Thick Disks in the Accelerating Expanding Universe Dominated By Dark Energy

In this article, we study the structure of the general relativistic thick disks in the accelerating expanding universe which is dynamically dominated by dark energy. By applying a conformal transformation on the metric of a thick disk in isotropic coordinates of a static universe, we study the disk in the Friedman-Robertson-Walker ( F R W ) spacetime of an expanding universe. Also, we investigate the structure of a thick disk in a dynamical state by solving Einstein equations in the presence of cosmological constant Λ. Moreover, modified mass and energy densities of the thick disk, as well as its radial, azimuthal, and vertical pressures, are examined as the functions of time. Furthermore, we check out energy conditions for the relativistic thick disks in the expanding universe.
