Slow rotation of radiating viscous-fluid Universe coupled with scalar field

  • Manihar Singh Koijam


Investigations are being made on slowly rotating models of radiating viscous fluid coupled with scalar field in spherically-symmetric Einstein Universe, and some new analytic solutions are found to substantiate the possibility of the existence of such universes. The nature and role of the rotational velocity Ω(r, t) which is related to the local dragging of inertial frames and that of matter rotation ω(r, t) are studied. We also discuss the effects of the radiation field and the scalar field on the rotation. Rotating models which are expanding are obtained, where in all the cases the rotational velocities are found to decay with the time; and these models may be taken as good examples of real astrophysical situations.
