چکیده
We investigate gravitational collapse of thick shell fluid in the isotropic homogeneous universe without radiation described by Einstein gravity with cosmological constant. construct analytic solutions this kind interpolating Friedmann-Lemaitre-Robertson-Walker (FLRW) metric and de-Sitter Schwarzschild black hole one Gullstrand-Painlev\'e one. After determining scale factor for a perfect coexisting constant, we determine orbit collapsing shells from continuity condition density perpendicular component pressure at interface. However cannot fix when there does not exist inside shells. In case an equation state consisting near surface. Finally confirm that total energy defined arXiv:2005.13233 is independent given time evolution system.

Nonadiabatic Charged Spherical Gravitational Collapse
We present a complete set of the equations and matching conditions required for the description of physically meaningful charged, dissipative, spherically symmetric gravitational collapse with shear. Dissipation is described with both free-streaming and diffusion approximations. The effects of viscosity are also taken into account. The roles of different terms in the dynamical equation are anal...
متن کاملGravitational Collapse of Perfect Fluid
The spherical gravitational collapse of a compact packet consisting of perfect fluid is studied. The spacetime outside the fluid packet is described by the out-going Vaidya radiation fluid. It is found that when the collapse has continuous self-similarity the formation of black holes always starts with zero mass, and when the collapse has no self-similarity, the formation of black holes always ...
متن کاملGravitational Collapse of Barotropic Spherical Fluids
The gravitational collapse of spherical, barotropic perfect fluids is analyzed here. For the first time, the final state of these systems is characterized without resorting to simplifying assumptions such as self-similarity using a new approach based on non-linear o.d.e. techniques. Formation of naked singularities is shown to occur for solutions such that the mass function is sufficiently regu...
متن کاملGravitational Collapse of Spherical Interstellar Clouds
In this paper, the gravitational collapse of spherical interstellar clouds is discussed based on hydrodynamical simulations. The evolution is divided into two phases: former runaway collapse phase, in which the central density increases greatly on a nite time scale, and later contraction, associated with accretion onto a newborn star. The initial density distribution is expressed using a ratio ...
متن کاملGravitational Collapse of Homogeneous Scalar Fields
Conditions under which gravity coupled to self interacting scalar field determines singularity formation are found and discussed. It is shown that, under a suitable matching with an external space, the boundary, if collapses completely, may give rise to a naked singularity. Issues related to the strength of the singularity are discussed.
