On isotropic cylindrically symmetric stellar models
B. C. Nolan, L. V. Nolan
We attempt to match the most general cylindrically symmetric vacuum space-time with a Robertson-Walker interior. The matching conditions show that the interior must be dust filled…
Physical interpretation of gauge invariant perturbations of spherically symmetric space-times
Brien C. Nolan
By calculating the Newman-Penrose Weyl tensor components of a perturbed spherically symmetric space-time with respect to invariantly defined classes of null tetrads, we give a phys…
Generalisations of the Einstein-Straus model to cylindrically symmetric settings
Filipe C. Mena, Reza Tavakol, Raul Vera
We study generalisations of the Einstein--Straus model in cylindrically symmetric settings by considering the matching of a static space-time to a non-static spatially homogeneous…
The role of anisotropy and inhomogeneity in Lemaitre-Tolman-Bondi collapse
Filipe C. Mena, Brien C. Nolan, Reza Tavakol
We study the effects of shear and density inhomogeneities in the formation of naked singularities in spherically symmetric dust space--times. We find that in general neither of the…
