Phenomenological Scaling Relations for SQM Stars with a Massive s-Quark in Gravitationally Strong Magnetic Fields under the Spherical Symmetry Approximation
Łukasz Bratek, Joanna Jałocha, Marek Kutschera
Scaling relations with the bag constant parameter are investigated for Strange Quark Matter (SQM) stars in the presence of gravitationally strong magnetic fields minimally coupled…
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…
Oscillating Strange Quark Matter Objects Excited in Stellar Systems
Marek Kutschera, Łukasz Bratek, Joanna Jałocha +2
It is shown that strange quark matter (SQM) objects, stars, and planets, can very efficiently convert the mechanical energy into hadronic energy when they oscillate. This is becaus…
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…
Magnetic flux density from the relative circular motion of stars and partially ionized gas in the Galaxy mid-plane vicinity
Joanna Jałocha, Łukasz Bratek, Jan Pękala +2
Observations suggest a slower stellar rotation relative to gas rotation in the outer part of the Milky Way Galaxy. This difference could be attributed to an interaction with the in…
Velocity dispersion as a factor modifying the distribution of mass in disk-like galaxies -- an example of galaxy UGC 6446
Szymon Sikora, Łukasz Bratek, Joanna Jałocha +1
Within the disk model framework used to approximately describe flattened galaxies, we develop an iterative method of determining column mass density from rotation curve supplemente…
