We study static solutions of the Tolman-Oppenheimer-Volkoff equations for spherically symmetric objects (stars) living in a space filled with the Chaplygin gas. Two cases are considered. In the normal case, all solutions (excluding the de Sitter one) realize a three-dimensional spheroidal geometry because the radial coordinate achieves a maximal value (the 'equator'). After crossing the equator, three scenarios are possible: a closed spheroid having a Schwarzschild-type singularity with… Expand

The Chaplygin Gas Equation of State for the Quantized Free Scalar Field on Cosmological Spacetimes
In this paper, we try to answer the question whether the quantized free scalar field on a spatially flat Friedmann–Robertson–Walker (FRW) spacetime is a matter model that can induce a Chaplygin gasExpand
Thin-shell wormholes from the regular Hayward black hole
We revisit the regular black hole found by Hayward in $$4$$4-dimensional static, spherically symmetric spacetime. To find a possible source for such a spacetime we resort to the nonlinearExpand

We study gravitationally collapsing models of pressureless dust, fluids with pressure, and the generalized Chaplygin gas (GCG) shell in (2+1)-dimensional spacetimes. Various collapse scenarios areExpand
Analysis of the cosmological Oppenheimer-Volkoff equations
We formulate the Oppenheimer–Volkoff equations with nonzero cosmological constant, Λ. We analyze the behavior of solutions (under mild assumptions on the equation of state). We prove that solutionsExpand

Rapid interstellar travel by means of spacetime wormholes is described in a way that is useful for teaching elementary general relativity. The description touches base with Carl Sagan’s novelExpand
Stability properties of some perfect fluid cosmological models
Flat Friedmann-Robertson-Walker (FRW) perfect fluid cosmologies can be reproduced as particular solutions of suitable field-theoretical models. Here we investigate the stability of perfect fluidExpand

We study the role that tachyon fields may play in cosmology as compared to the well-established use of minimally coupled scalar fields. We first elaborate on a kind of correspondence existing betweenExpand
Regular phantom black holes.
It looks possible that the Universe has originated in a phantom-dominated collapse in another universe, with KS expansion and isotropization after crossing the horizon, and possible generalizations include k-essence type scalar fields (with a potential) and scalar-tensor gravity. Expand
