Cylindrically symmetric radial accretion onto a Levi-Civita string-like source
Łukasz Bratek, Joanna Jałocha, Marek Kutschera
Radial steady-state accretion of polytropic matter is investigated under cylindrical symmetry in the Levi-Civita background metric. The model can be considered as a cylindrical ana…
Nakedly singular counterpart of Schwarzschild's incompressible star. A barotropic continuity condition in the center
Łukasz Bratek, Joanna Jałocha, Andrzej Woszczyna
A static sphere of incompressible fluid with uniform proper energy density is considered as an example of exact star-like solution with weakened central regularity conditions chara…
A class of space-times of non-rigidly rotating dust
Lukasz Bratek, Joanna Jalocha, Marek Kutschera
We find a class of exact solutions of differentially rotating dust in the framework of General Relativity. There exist asymptotically flat space-times of the flow with positive mas…
