FORMATION OF VOIDS FROM NEGATIVE DENSITY PERTURBATIONS .2. THE ROLE OF ROTATION AND NONSPHERICAL PERTURBATIONS

De Araujo & Opher have recently studied the formation of voids from negative density perturbations taking into account a series of physical processes during and after the recombination era. In the present investigation we study the effects of nonspherical negative density perturbations and rotation on the dimension and density of the ''voids.'' We find that, although the resultant '' voids '' are not significantly affected by eccentricity, rotation has an important effect on their final dimensions and densities. For example, for the rotational energy approximately 10% the gravitational energy for M = 10(12) M., we find that the present size increases due to rotation a factor approximately 2 and the density decreases b a factor approximately 10.
