Cylindrically Symmetric Spiraling Accretion in Power-law and Logarithmic Potentials
Łukasz Bratek, Joanna Jałocha, Marek Kutschera
We study cylindrically symmetric steady-state accretion of polytropic test matter spiraling onto the symmetry axis in power-law and logarithmic potentials. The model allows one to…
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…
Is dark matter present in NGC4736? An iterative spectral method for finding mass distribution in spiral galaxies
Joanna Jalocha, Lukasz Bratek, Marek Kutschera
An iterative method for reconstructing mass distribution in spiral galaxies using a thin disk approximation is developed. As an example, the method is applied to galaxy NGC 4736; i…
